Added Grunt tasks - litmus test

* "grunt test" to send tests to litmus. (someone needs to test this
because I don't have a litmus account.)
--> Note the config option(litmus) may cause an issue

* "grunt dev" to live reload your docs.

Considering adding the following:
1).  sass support
2).  improved inlining tool/logic (? without shell ?)
3). hbs templating with various layouts (much further down the road).
--> examples = standard templates + video + more ;-)
