Version 1.4

This release converts timestamps in the database to UNIX epoch time and
creates an index on them. The queries generated by scoop(1) with -a, -b
and -D now take advantage of the index.

After running the database migration with litterbox -m, running
"VACUUM;" from "scoop -S" will reclaim space previously used by string
timestamps.

This release fixes issues with MODE parameter handling and MOTD
handling.
