[vim] A quick hack to just autosave on buffer modification instead of sending events through the node server.

The most rudimentary form of html LiveEdit is working! :)

TODO's
1. Figure out what the problem with just using setContent through devtools api for a document resource
2. Navigate away from the NPAPI stuff. Run all filewatching through the node server.
3. Write something for sublime to send keyboard events through the same interface as vim is
