[Lazarus] Delphi converter improvements

[Juha Manninen]

Hi,

The converter is improving gradually in SVN trunk.
Converting the source code works better and there is an option to support 
Delphi compatibility with conditional compilation.

For Lazarus / LCL code, "Windows" is now replaced with "LCLIntf", "LCLType" 
and "LMessages". 
I realized there are other windows specific units like "ShellApi". What should 
I do with it?

I haven't touched the missing components / properties problem yet. It needs 
much work.

Feedback is welcome.

Regards,
Juha
