[FR-devel] updated foxservices

[Rich Kilmer]

Changed FoxServices to use the CommandManager instead of a separate
structure.  This simplifies the architecture to have a single mechanism
for reusable behavior (commands).  The names of the commands are:

App/Services/FileOpen -> return filename or nil
App/Services/FileSaveAs(filename) -> return ['cancel'|'save', filename]
App/Services/FileClose(filename) -> return 'yes'|'no'|'cancel'
App/Services/MessageBox(title, message)
App/Services/Shutdown

This way the "FoxServices" name still makes sense, and the they are
still, technically "services" but they are "Service Commands" (or
something like that.

I will now flip to solidifying the editpane and getting debugger
working.  Sorry for that delay.  I need sleep now, but will get to them
in about 8 hours.
