[lazarus] Updates

[Mattias Gaertner]

H. to all,

Before someone misses the object inspector: This is not a bug, but a feature.
The OI will show, when a form is loaded. 


Other updates:
- splittet main.pp into 
  main.pp, mainbar.pas, basedebugmanager.pas, debugmanager.pas
  This was a medium code move and clean up. 
  I reordered the open/save file logic, and fixed some bugs. 
  It is possible that this produced some new bugs. Plz report them.
- fixed class completion of abstract methods
- fixed TSynEdit mouse move selection
- fixed editor options "double click line"
- new keys for keymapping: moving cursor keys
- new function: Search->Goto include directive. Jump from an include file to
  its include directive.
