Fixing and upgrading Fl_Preferences (#374)

* Added filename function to Fl_Preferences

Static function to get filename before opening.
Member to get filename after opening.
Bug fixes for memory mapped preferences.

* ERROR is a macro on Windows, don't use it

* Added Fl_Preferences::dirty().

User can now check if the database will be written
when flushed or destroyed.
Flush returns a crude error code.

* Fl_Preferences::get binary data returns # of bytes read.

* Verified group deletion code

* Fl_Preferences ignores locale.

This will make .prefs files interchangeable
between different computers.

* Updating the Preferences Mode to ignore locale.

* Fixes in docs.
