Lots of changes to support loading alternative color name database.

Browse source 
You can switch database by just loading the new one; the list window
and nearest colors adapt to the new database.

Some reorganizing of code.  Also, the name of the database file is
stored in the ~/.pynche pickle.  If it can't be loaded, fallbacks are
used.
