[Lazarus] Refactor Menu

[Juha Manninen]

Hi

I have refactored Lazarus main menu by adding a Refactor menu. :-)

I also added a Source menu.
Eclipse and some other IDEs have done the same thing.

Sometimes it is difficult to decide under which menu a menu item belongs.
"Enclose Selection ..." is now under Refactor menu. It could be under Source 
menu together with "Comment Selection ...", too.

Later the editor local menu will have Source menu, and some checks will be 
added to disable the entries when they can't be used.

More ideas?


Regards,
Juha
