Consolidated coverage report generation into one rake command.
Added diff coverage reports using diff-coverage tool.
Clean the report directories before each test run,
to ensure we don't get coverage results from a
previous test run.
Added diff-cover as a requirement (installed from github)
Use from_descriptor instead of from_xml to make ErrorDescriptor
Use full descriptor when showing errors, not just the model data.
Fixed issue with code mirror editing

It turns out that code mirror things can be edited.  Once the div is clicked, a new text area appears that can be obtained and sent keys
Made finding place to click a bit nicer
Fixed bug in tests.rake in which rm would be called with no args.
Updated to current tag of diff-cover
Merge branch 'master' into will/diff-cover-integration
Added diff coverage printout to rake coverage command
Added warning message when no coverage information found.
Added comments to tests.rake
