+ Increase hash iterations for heimdal-history by about 10% to maintain
+ the time required for a password hash at about 0.1 seconds on not
+ horribly modern hardware. This will affect newly-stored history
+ entries but will not invalidate existing password history entries.
+
+ Explicitly erase the copy of the password made in the Heimdal plugin
+ before freeing memory.

+ Add a spec file for building RPMs, contributed by Daria Phoebe
