update medication schema and example
upgrade Rails, for the second time in a week.  this time to 3.2.11.
silence annoying rails admin unit test message
silence Rack deprecation messages during tests

When we upgraded to Rails 3.2.11 it pulled in a new rack which printed
an annoying deprecation message during unit tests.  Removed the static
asset config for tests to quiet it.  In practice it won't make a
difference in test performance and it will keep me from going nuts
looking at spurious messages.
Merge branch 'atwork'
