Started the rewrite to use a jQuery plugin with multiple options/ full configurable

still need to add AJAX and css transitions
Added mousewheel as a dependency. Moved the if statement as a call back to the slideUp callback

Will be changing this so can use css3 transitions/animations instead of
jQuery animation. Still need to work out the bug where callback is
firing multiple times. Firefox does not like to reload page until mouse
has scrolled down first. May use mouse movements in addition to touch
and mousewheel
Add README.md
Cleaned up README
Added dependency and Examples to readme
Checking a boolean each time mousewheel event is fired. Now callback is only fired once.
Added class to element when text is there.

Updated readme for current know issues.
Updated assets to use hook as spinner, using css3 animations to spin it.
scroll wheel now optional. set to false by default
Removed plugin call at beginning of script, cleaned up from jshint, added min file

Also added my name to authors.
Merge pull request #11 from agirton/master
