remove pig latin versions for a name that is more clear

[trescube]

Pig latin makes for very confusing code and yet another barrier to entry for devs. This PR changes efineday and equireray with the more readable testLoaderDefine and testLoaderRequire.

If these names don't quite capture the nuance of their purpose, let me know and I'll update.

What we are renaming are the global require and define provided by Ember's loader, so emberLoaderRequre and emberLoaderDefine would be more accurate names, and maybe emberRequire and emberDefine for brevity's sake.

This should be tested (npm linked) in the Hub app . I know we will need to at least change the places we've done this #95 (comment), as long as we are continuing to do that.

If you can confirm that it works over there, I'll approve this and cut a release that you can PR to the Hub app. In other words, I'm not opposed to this as long as I don't have to do anything other than cut a release.
