[lazarus] Updates

[Mattias Gaertner]

Hi all,

OpenFileAtCursor:
I added the path of the active file to the search path and made it windows compatible. 


Small changes:

- added perl hilighter
- added Yes-To-All to Search&Replace
- replace dialog will now try to not hide the found location
- open file will not try any longer to open lrs files as lfm files.
- find text should now focus the text field
