No bower support since version 1.2.4

[dfahlander]

Now, since build outputs have been removed from the repo (to make it easier to collaborate and merge from different branches), bower package wont work anymore.

People being dependent on bower, please comment on this. Might use the same workaround as I do in Dexie - to create a release script that automatically checks in build output onto a separate branch and uses that branch as the github release = bower release.

If no one is using bower, we should just delete bower.json from this repo.
