Generate enum types from source

It became a little unwieldy to create the enum types manually via
g_enums_register_static(). This changeset creates the types from enum
definitions in public headers using glib2-mkenum.

Be sure to include uca-enums.h in every source file that needs to know GObject
enum type.
