[lazarus] Updates

[Mattias Gaertner]

Hi all,


- editopts->codetools->autotooltipsymbtools activated
  
  This option activates or deactivates the smart hints in the source editor.
  These hints are currently only showing the word underneath the mouse cursor,
  but eventually they will show the declaration just like Delphi.

- added syntax highlighters (xml,lfm) for
  *.lfm *.dfm *.xfm *.xml *.xsd *.xsl *.xslt *.dtd files.
- added error position and message to all of TCodeToolManager.
- fixed mem leak in editor options (mapped color attributes)
