CodeMirror update

Latest master of CodeMirror doesn't contain built codemirror.js in the lib directory: https://github.com/codemirror/CodeMirror/tree/master/lib

Since we'll definitely want to upgrade for next version there are two options:

a) add a task to our grunt scripts that'll build codemirror.js by calling npm run build in the CodeMirror submodule
b) use CodeMirror as npm dependency

Let me know which solution you prefer.

Voting for b)

My vote for 'b'.
Off topic - We should do the same even for 'tern'. I will work on the PR where we are moving the entire JS analysis to node.
