Simplified exports in blueprints

[mriska]

This PR changes the blueprints from using a named variable to doing direct exports of the code. In addition to being more easy on the eyes, it fixes a problem with the compiled javascript file containing an undeclared variable in newer versions of the CoffeeScript compiler.

Fixes #135
Fixes #134

I have tested to create all of the blueprints changed:

ember g adapter foo-foo
ember g component foo-foo
ember g controller foo-foo
ember g helper foo-foo
ember g mixin foo-foo
ember g model foo-foo
ember g route foo-foo
ember g serializer foo-foo
ember g service foo-foo
ember g transform foo-foo
ember g util foo-foo
ember g view foo-foo

And the tests pass with the exception of view which I assume is due to the fact that a fairly recent Ember version is used which no longer supports views. I guess this blueprint can be removed at some point unless we want to keep it for people using it with older Ember version. On the other hand a case can be made for not helping them to create code that is deprecated in newer versions of Ember.

I didn't know there were node tests in here as well, I'll get those fixed.

@kimroen pushed updated code with amended tests. There is only one failure (beta) in Travis right now that looks like it needs poking to be rerun.

@kimroen, All builds are green now, do you think it should be merged, or are you still missing something?

In the original blueprint this is a named function, but I haven't found a way to export a named function with the CoffeeScript syntax, so I'm not sure if it can be done.

[mriska]

@kimroen I think you can do that with

export <%= camelizedModuleName %> () -> 

Like we have done here: https://github.com/kimroen/ember-cli-coffeescript/pull/137/files#diff-f9c146914b83a86c6a8d484dc1d877d6R4

I'll do some testing and create a PR for that.

This looks good - thanks again! 🎉

I noticed now that this missed some files, like the initializers.

@kimroen I'll check those out later today/tonight

@kimroen Created a new PR #139 that fixes initializer blueprint.
