Added minor comments for the minimise/maximise code on the overview
Removed now unused scroll dep
Updated bower to be project relevant
Merge pull request #30 from MarcelCutts/master

Minor tidy ups
Added play and pause icons (courtesy of http://www.flaticon.com/)
Added a play / pause button to the slider. This will need repositioning.
Put the icons in an appropriate position on the slider.
Renamed function to toggleAutoplay for clarity.
Is slider is now brushed, autoplay will be flagged as false.
Moved the autoplay functionality into a service - this avoids the need to use the parent scope in the directive (dodgy coupling).
