Add epic editor to bower and templates

Added epic editor to the posts section so that authoring Markdown is a little easier.  #62 

I used bower to install and manage this package. a simple bower install in the root will pick this up. However I can download the package if we want to not use bower.
Can we move this inside of the main javascript file?  Or maybe even use require.js to pull in a single individual javascript file to contain this stuff?  Like to try and limit inline javascript to like a line or two max within html templates.
