[Cuis] New Commit: FileMan adoption and tweaks

[Juan Vuletich]

Hi Folks,

I've just updated github. I did many changes, to adopt FileMan almost 
everywhere in Cuis and core packages.I did a few changes to FileMan and 
the API. The one you might notice is that I've made FmFileEntry and 
FmDirectoryEntry siblings, under a new FmEntry. Now, each class is more 
specific: FmFileEntry doesn't handle Directory responsibilities (like 
creating files in it) and FmDirectoryEntry doesn't support File 
responsibility (like creating a FileStream on itself). I think it is 
much cleaner this way. The change you might need to care about is that
'dirName' asDirectoryEntry / 'subdir'
answers an FmDirectoryEntry
and the new #//:
'dirName' asDirectoryEntry // 'filename'
answers an FmFileEntry.

Please adapt your packages to the new FileMan API, as the old 
FileDirectory hierarchy will be deprecated soon, and later removed from 
Cuis.

Oh, this commit also includes new versions of TerseGuide and 
ClassCommentBrowser by Dan Norton. (Thanks Dan!)

Cheers,
Juan Vuletich
