Removed functions from .each loop

Reduced the number of times the $(window).scroll & stickyMenu functions
were being called by removing them from the .each loop and placing them
outside.
Each function was called 'n' times where 'n' is the number of
$smintItems
Also added a check for smint-disableAll for external links
Added Hashtag support

Can now click and open in a new tab,
Copy link url to scroll directly to the section needed.
Added demo folder back

Demo folder is quite useless when we can use the gh-pages branch itself.
Increases changes by one more file each time you update both.
