[lazarus] CVS changes - BringToFront / SendToBack implemented

[Michal Bukovjan]

Hello all,

I just commited BringToFront / SendToBack, which works on GTK.

I cannot test it on anything else (Win32). The old code is commented 
out, the new one could also work on win32 - if someone can test, I would 
delete old code as well.

BTW, the LM_BRINGTOFRONT is not needed at all now (no platform specific 
code is used).

Have fun,

Michal Bukovjan
