added touch and open on hover

[tihomirmagdic]

Yesterday I've forked library and added some code:

• to open/close the sidebar on mouse enter/leave (property openOnHover) with delay before opening/closing (delayBeforeOpen, delayBeforeClose)
• to enable sliding with touch events (enableSliding) with threshold (thresholdToClose)
• animation on backdrop

Also, demo is updated accordingly added properties.

Maybe you find some interesting code inside.

Awesome! It'd be great if this was broken up into multiple PRs for the different features though.

will this ever be merged? open on hover seems to be awesome. hey @arkon, do you have plans to develop it feature in the future?
