Release Name: 0.12.1

Notes:
This release changes the gem dependency on ncurses to ncursesw, which
allows the gem to install cleanly on Ruby 1.9.

The new sup-import-dump program applies labels to an existing index,
which could be done with sup-sync before 0.12.


Changes:
* Depend on ncursesw rather than ncurses (Ruby 1.9 compatibility)
* Add sup-import-dump
