Deprecated commands no longer needed.

[achambers]

Deprecated the following commands:

• ember deploy:index
• ember deploy:assets

As well as commands from the former ember-cli-project:

• ember activate
• ember deploy:versions

Closes #50

[lukemelia]

nit: "deprecated" means still works but will be removed in the future. We should probably refer to this as "no longer supported"

[achambers]

Ah, good point.

[lukemelia]

How will this work with ember help? Ideally these commands would not appear. Is that possible?

[achambers]

@lukemelia I modify the command descriptions to add [NO LONGER SUPPORTED] in red text. So it looks something like this:

ember activate <options...>
[NO LONGER SUPPORTED] Activate a deployed version of index.html

I'd need to look deeper into how ember-cli creates the commands but I imagine, to remove them from ember help would mean that they can't be executed. Which kind of defeats the purpose of adding the message in the first place.

@achambers sounds good. doesn't look like ember-cli has a way to hide a command from help.
