Make --keep-states more useful by actually removing states.

Browse source 
Fixes #70.

We don't modify the behavior of mask_keep_states(), because it is
actually useful in some algorithm to remove states without renumbering
all the other states.

* src/bin/autfilt.cc: Call purge_dead_states().
* src/tgbatest/maskkeep.test: Adjust.
