[lazarus] TOpenDialog Multiselection (+Updates)

[Mattias Gaertner]

Hi all,

Thx to Michael the TOpenDialog has now an Options property. The first flag is ofAllowMultiSelect. Turn this on and you can select multiple files. (Open files in the IDE is already using it).

Note: the multiselection under gtk is not very handy. AFAIK It is not possible to deselect everything, you have to deselect step by step. (Or click cancel and start again).
Nor does Ctrl or Shift work.


Bugfixes:
- fixed close->change on disk->open old code bug
- implemented DestroyCaret
- carets are now auto destroyed, when client widget is destroyed
- caret timers are stopped if caret becomes invisible
-> These caret bugs were responsible for IDE crashes on closing files.
