Removed unused Base64 library.
Remove IE8 support with document.write
Replace cb() with CustomEvent(). This is really the main reason for the fork, though I will do other things with it yet.
Update Readme
Remove IE-related code (also, replace a few tab characters)
CustomEvent() is mostly working.
Add to Readme
Some cleanup.
Stylistic changes in binaryajax.js.
Remove AJAX handlers. They should be seperate from the core library, really.
