[lazarus] New things

[Mattias Gaertner]

Hi all,

New things:
  - you can now set the unit output directory in the Run->Compiler options

  - There is now a basic 'Find Declaration'.
    It understands:
      var/type/const definitions, classes, records, variant records, enums,
      'self' identifier, methods, identifier types, point operator, pointers,
      ^ operator, with statements, forward classes
    Not yet implemented:
      class ancestors, interfaces, used units, bracket operators,
      proc definitions, operator overloading, ...

Fixes:
  - codetools and compiling will no longer produce zombies
