Rename events() to getEventManager()

[akrabat]

Also updated rest of code throughout framework.

Obviously, this will affect a lot of code used elsewhere...

@akrabat this is to reduce inconsistency with other accessors in the format getSomething()? Along those lines I'd suggest to apply these changes to Zend\Http\Request as well since there are getters Request::uri(), Request::query(), Request::post(), Request::cookies(), Request::file(), Request::server(), Request::env() and Request::headers(). I quickly browsed through some other code and did not stumble upon other places where this type of naming is used, but perhaps there are even more components?

@juriansluiman If you want to see that happen, it MUST happen by Tuesday, 3 July 2012. Otherwise, it will have to wait for 3.0. (Also, requires separate PR, obviously).

@weierophinney I wrote an email to the ML, to see whether others would agree. If so, I will PR for this change.
