Adds basic bower package file

I've created a basic bower package install file. You'll obviously need to make your own changes to it, but I tried to put as much info related to your repo in it as I could.

I'd advise some kind of clean up on the repo a little, not that it's a major issue. Using bower to install the plugin means that users, like me, can use gulp and hook into the main bower file to bring only what's needed into the main project files.

I'd make the search.json file a dependancy so people can deal with the file separately to the main plugin.
