Highights of the Changes:
- What was previously the editor is now input
- Editor is now SenseEditor, a (somewhat) generic class that inherits from AceEditor and mixes in RowParser. will eventually be used by the output as well
- input is an instance of SenseEditor that has an autocomplete object at `input.autocomplete`
- Moved all network/sendToES logic into the app module
- History no longer does any manipulation of the input, that is handled by the app (reduces inter module dependencies)
- help popup and welcome popup are now seperate modules
- welcome popup is not loaded unless needed
- SenseEditor#getCurrentRequestRange and SenseEditor#getCurrentRequest are now async, and will return their value once tokenization has completed.
- Replaced "Copy as cURL" functionality, using ZeroClipboard for now.
