[lazarus] maskedit vs mask

[Andrew Johnson]

I just tried porting a basic db test app from delphi to lazarus with my
contorls, and found that at least in my D4 there is no MaskEdit.pas, its
called Mask.. Do we want to change the name for compatibility? I know we
have to include extra files in a few cases, but not sure how wise name
changes are if we want ease of conversion. Its not a big deal to me
really, just thought I should make sure it gets brought up. :)
