Add bower configuration file

[mazurov]

Bower is a package manager for the web. Estraverse is already registered. So it will be good to have escope registred too. For that we need:

• to have bower.json configuration file in the github repository (with estraverse dependency record)
• install bower sudo npm -g bower
• And register package bower register git@github.com:Constellation/escope.git

It's possible to register package without bower.json file (like it was done for estraverse), but in this case we will lose dependency information.

OK, LGTM. I'll merge it. Thanks

bower/bower#120 (comment)

There is some issue with the bower registration (wrong git endpoint, that gives us an error for bower install escope). May be the registration command should be bower register git://github.com/Constellation/escope.git. In any case, currently it's no way to update it from our side and I've created an issue.

Oh, sorry for mis-registration.
Thanks, after that issue is accepted, I'll register escope more carefully.

I think this is the bower registration fault — they need to check the url first.
