Add task to remove prototype extensions

[tim-evans]

Since this seems to becoming the default, having a task to remove decorators that use prototypes would be really nice :3

See:
ember-cli/ember-cli#3645
emberjs/guides#110

[stefanpenner]

ya good idea, this should be a relatively simple transformation.

I pushed a PR to transform CP and observers #10

Next steps would be to transform more prototype extensions like

'hello %@'.fmt('world')

Is there a complete list somewhere?

[tim-evans]

@kamal I think fmt should be removed and quasi literals are used. But that's up to the core team.

[stefanpenner]

@tim-evans I would be on board with that. If someone opens an issue I'll bring it up this next meeting for discussion

@stefanpenner woot

Just released the new command thanks to @kamal!

npm install ember-watson@0.2.0 --save-dev
ember convert-prototype-extensions

[abuiles]

Actually leaving open until we have figured how to transform other parts of the extensions.

[tim-evans]

Supporting on would be nice too :)
