* Update plugins/codemirror-editor from branch 'master'
to c97e2806532cff00fea6424cde0d440f9ea5016d
- Fix codemirror-editor build
Moves the polymer dependency out of the plugin and into the test, as it
is injected during the Gerrit build step (and bower install is not run
during the Gerrit //plugins:core build step).
