creating a new database by presenting a sheet, allowing the user to specify the table name and encoding.
- Allowing the user to specify the table encoding partially addresses issue #161.
- Implementing interface validation in the form of not allowing table creation without a name also removes the need for lots of error checking and presenting these errors to the user.
- In addition to the above the ability to specify the initial field name, type and length (if applicable) of a new table can now be done on the same sheet, but is yet to be implemented.
- Also did a general tidy up of TablesList.[hm].

- added a backtickQuotedString: method to SPStringAdditions
- created the file SPArrayAdditions for a componentsJoinedAndBacktickQuoted: method
In the future, we should use backtickQuotedString: to quote identifiers like this:
[NSString stringWithFormat:@"SELECT * FROM %@", [tableName backtickQuotedString]]

- Removed refresh tables menu item - refresh button right beside it.

Issue #155)
- Added basic support for viewing, filtering, and editing BIT columns (resolves Issue #127 in basic form)
- Rewrites selection/save handling. Rows are now only written to database if their content has changed, resolving a long-standing complaint; row selection and editing has also been improved, improving edit/save interaction (fixes Issue #157) and allowing re-editing of the row on failure (fixes Issue #115). Hopefully also addresses #Issue 131, and improves Issue #172.
- Hides the console window when the associated document window closes

the damage caused by r333, making views viewable again, and extends support by preventing errors in the info pane, by drawing views with a different icon to easily differentiate them, by making all source/index information non-editable to match GUI to behaviour, and to tweak the interface slightly to match.

- Significantly reduce the queries that have to be performed, improving lag - especially over slow connections (Issue #118; see new controller info under headline code changes).
- Fix Issue #117 properly (export numeric quoting - we now have access to column types and so can quote appropriately).
- Fix Issue #145 (loss of unsigned/null/default attributes when reordering columns).
- Fixes Issue #90 (support for filtering DECIMAL column types)
- Improve table scrolling speed when the table contains long items. (Added a NSFormatter to automatically truncate strings > 150 chars for display purposes only)
- Improved SQL compatibility - for example /* C style comments */ are now correctly ignored in imports and custom queries.
- Add text and symbols emphasising that the table info pane / status view row count is an approximation (partially addresses Issue #141)
- Fixes a major memory leak whenever opening or scrolling tables containing text/blob data.
- SQL import is now faster (SQL parsing part is 3x faster).
- Speed up SQL export (1.5x faster for numeric data; 1.1x faster for string data) and slightly speed up CSV export (~1.1x faster).
- Display sizes on the status view using the byte size formatter, as per table info pane.
Headline code changes:
- Add a new NSMutableString subclass, SPSQLParser. See the header file for documentation and overview, but in short it's a centralised place for SQL parsing. Centralises and improves parsing, improves comment support, improves quoting support. Despite the improved featureset this is also faster than the previous distributed implementations - for example, when used to replace the old splitQueries:, > 3x speedup.
- Implement a new controller which handles a structure and status cache for the current table, and provides structure parsing for specified tables. This cache is now used throughout the code, reducing the queries that have to be performed and providing additional information about the table structure for use; I think it also improves column type format slightly.
- The table info pane and the status view now draw all their data from the cache.
Tweaks:
- Table encoding is now detected directly instead of being derived from the collation - increased accuracy and cope with the DEFAULT encoding.
- Comments and formatting cleaned up in bits I was working on, obviously.
- A couple of methods - particularly [tablesListInstance table] and [tableDocument encoding] - have been renamed to avoid conflicts and fix code warnings.
Future improvements now possible:
- As we now have access to column types and other information, we can provide per-type behaviour where desired.
- The table parsing doesn't currently pull out comments or table indices, together with one or two other attributes. Some of this would be useful for display; some, such as indices, could be used to draw the table structure view as long as we're happy discarding a couple of columns (ie cardinality!)
