Feat/double bower

There are two .bowerrc  files in our project, one in client/user, the other in client/admin
They have to have the same name
Likewise, there are two bower.json files in the above two directories, and these files also have to be identically named
To set up your dev environment, you need to run bower install inside admin, and then again inside client

Our gulpfile no longer handles bower installation
Our .gitignore is updated to reflect this change. 
Package.json is left unharmed

Note that we will need to fix this as we get closer to deployment
