Merge branch 'supplies'
Add supplies to master list. Fixes #367

Note that the added supplies are _not_ selected by default. PCMOs will
need to opt in to provide them.
Disable PCV ID check for PCMOs. Fixes #368

since they don't have a PCV ID.
Sort supplies by name asc everywhere by default

I noticed the supply list in the email was being sorted by id / creation
time. This seems more appropriate.
Guard against no phone_number params
removed .rvmrc
Updated Gemfile to ruby 2.1.4

Don't require PCV ID for @peacorps.gov password resets. Fixes #379
Add help text reflecting password reset requirements #379
Merge branch 'supplies_mgmt' of https://github.com/dhaskew/medlink into dhaskew-supplies_mgmt
Minor test cleanup

The held `cbox` reference seemed to mask the actual test, since it
wouldn't necessarily re-find the checkbox on the new page. This extracts
a (hopefully slightly more readable) helper function.

Also, trimmed some trailing whitespace.
Bump rvm version for Travis

The build was erroring because the .travis.yml and Gemfiles specified
different versions.
Merge branch 'dhaskew-supplies_mgmt'

Allows PCMOs to manage which supplies are available in their country
without needing admin access.
