Fixed minDragDistance
Merge pull request #70 from prud/patch-3

minDragDistance setting is not working
Added new snap.js events: close, open, expandLeft, expandRight, enabled, and disabled. Updated README to reflect this change.
Ensure css classes for left and right have been removed. Changing the orientation when the menu is open causes the class to remain even though the menu is closed.
Undo previous commit. Real issue was in the utils.klass.remove function. If other code adds additional classes *after* the snapjs-left or snapjs-right, remove will no longer work (or if the order changes and there happens to no longer be a space before the name).
