SVN commit 464484 by knight:

GUI: 

- Added basic syntax highlighting - Valid cell references in formulae are now coloured in as the user enters them, and a thin coloured border (a "highlight") is drawn around the area on the spreadsheet.  It is possible to change the size of a range referenced in a formula by dragging the size grip on the coloured border, but this is still work in progress.

- Changed cell text edit widget (KSpreadTextEdit) to respect line wrap settings of cell being edited.

- Cell text edit widget no longer has a border around it.  Ideally the cell edit widget should fit inside the cell,
so that the existing cell border can be drawn around it, but unfortunately the Qt 3 QTextEdit class has several pixels padding at the top and left sides, so the widget has to be slightly taller than the text itself.  This can be fixed during the Qt 4 port.

- Spreadsheet names in formulae are no longer case sensitive (Documentation needs to be updated to reflect this)
