[sugar] libabiword, libabiword-plugins, pyabiword and abiword merged

[J.M. Maurer]

Hi all,

I've merged libabiword, libabiword-plugins and pyabiword from OLPC with
the official Fedora AbiWord package. libabiword-plugins only existed in
OLPC-land, and has been retired.

Everything is built through koji now and joyride should build again. If
there are any problems (for example, dragging in too many deps on OLPC),
please let me know.

Sorry for all the build breakages in the process. It wasn't exactly a
trivial merge.

  Marc
