suggestion to move Vim mode into ace

[nightwing]

Hi,

it seems to me that moving vim mode into ace, will make it easier to develop and less hacky
it will also benefit ace by making it's keybinding mechanism more general

here i moved vim keybindings, except cli, into ace and made more modular
so that one can simply use editor.setKeyboardHandler as with other handlers

also making vim a handler itself not depending on stateHandler, would make things more clear.( though there can be some subtleties)

That is cool!

@sergi can you take a look at this? We would have to change the license of these files but that should not be a problem.

We still have to do some due diligence with the license change of the vim mode code. I would suggest moving this into a feature branch until this is resolved.

Please note that any build containing the vim mode right now would be GPL licensed.

I have it here: https://github.com/ajaxorg/ace/tree/vim

I would like to keep rebasing this branch to master instead of merging. Would that be ok for you?
