• added selectLineNumber:x to CMTextView to be able to select the line x

• added error highlighting of the first mentioned error
- if a "near message" error is provided select that message otherwise select the entire error line and scrolls to it
- if no "at line x" and no "near message" is given do nothing
- if a selection was given and the user pressed "runAll" destroy the selection before error checking; if no error was found reconstruct that selection (to be able to distinguish between "runSelection" and "runAll" plus selection)
* changed slightly the trigger for syntax highlighting/auto-uppercasing for better scrollToRange behaviour
