Bud 0.9.1 released

[Neil Conway]

Bud 0.9.1 can be found on Rubygems. This release includes two changes:

* Reject attempts to insert a tuple into a collection with more fields than are
in the collection's schema
* Previous behavior was to ignore additional fields, but this was found to be
error-prone
* Remove builtin support for BUST (web services API); this avoids the need to
depend on the json, nestful and i18n gems.
