BUGS
=====================================================================
- Delete():
1 - occasionally delete deletes too much, maybe when at begin of
line?
2 - when in an empty line, Delete() doesn't always merge lines
3 - line numbers aren't updated properly, may be related to 2.
4 - deleting lines leaves later parts of the list unaffected
--> just redrawing at least the next two lines doesn't seem
enough, strange, don't positions change?
- dmalloc shows duplicate deletion after merging two lines and
deleting the second half
TODO
=====================================================================
- Add word wrap to wxlwindow/wxllist.
- Cursor to mouseclick
- Focus feedback for cursor
- Selections
- More optimisations
