Added ability to trigger custom events on arbitrary selectors,  changed ajax calls to callback(response, evt) from callback(evt)

Conflicts:
	js/tinyDOM.js

Limited delegate event checking to root element specified by mu instead of bubbling to document root

Added functionality for delegated events, updated tests accordingly. Included Element.matches polyfill by github user elijahmanor

Fixed error function not being fired by reversing method call order. Also fixed previously unknown bug where an error would be fired for a 304 response (and presumably others)

Added an extra file (test.js) to store various tests under muTest, a php
file to respond to requests and an update for test.html to include
test.js

Noticed tinyDOM.min.js was a few versions behind, updated it

Removed comment that was the beginning of an attempt to document the
library as it evolved; that effort obviously fell to the wayside. Proper
documentation will occur when things are more complete.

tinyDOM can now tell between query strings and DOM abjects passed to mu, allowing better chaining with μ(this)

tinyDOM.ajax() now returns the XMLHttpRequest, as it should have to
begin with

Added a minified version of tinyDOM

Added ajax support as a utility function. All options are passed in a
single object, as well as an optional success and error function

Updated library symbol to (more appropriate) 'μ' and added an alias as
'mu' in case unicode isn't available in an editor for whatever reason
