Upgrade Ruby from 2.1.5 to latest version.

[jasnow]

As of March 30, 2015, Ruby version is 2.2.1.

• Change version in all config files, such as .ruby-version, .travis.yml, etc.
• Run bundle to create new gemset.
• Clean up warnings and errors.

Two loose ends:

• WARNING: Nokogiri was built against LibXML version 2.9.1, but has dynamically loaded 2.8.0
• Commented out one line in slim file. Tagged with "FIXME:". Use git grep FIXME to find it.

Why is input_html listed twice in app/views/application_drafts/new.html.slim file (line 54)?

= f.input :misc_info, as: :text, label: 'Anything else to add?', 
input_html: { rows: 4 }, hint:
'Address anything that you feel is relevant to your application and was not covered previously.',
input_html: { disabled: !application_draft.as_student? || application_draft.applied? }

Unclear how to fix it.

Ah, that must be a copy/paste error. Thanks for spotting it! Just put the rows: 4 in the 2nd input_html hash.

Show me the revised line and I will check it in and close this issue. THANKS...

Too confusing with closed PR so closing.
