• completion

- CTRL+ESC invokes the fuzzy search completion; eg:
i_s.pcss.  will show all fields from `information_schema`.`PROCESSLIST`. if no other matches are found; the search is a regexp ".*?i.*?_.*?s.*?\. …" etc. by using RegexKitLite which is much more faster than NSPredicate and can handle long regexps
- improved type display: if a type definition contains a , split it to avoid splitting of the tokenFields
- while insertion of an item and holding down the CTRL key the list keeps open to allow to insert more suggestions separated by ", " from the current list (very useful if one wants to insert only selected fields from a table)
