[FEATURE] Added Bower support

I'm currently working on a [custom Yeoman generator](https://github.com/tollwerk/generator-tollwerk) that will make it a breeze to scaffold a TYPO3 project the way we usually do it at [tollwerk](http://tollwerk.de). The generator will be able to pre-install TYPO3 extensions. I would love to let the generator install the FT3 extensions as well (flux, fluidpages, fluidcontent, vhs).

For this to work, the repositories need to include appropriate `bower.json` configurations (I did this as well with [some of my own extensions](https://github.com/jkphl/TYPO3-ext-squeezr) and it works like a charm). Once the configuration files have been merged into the repos, I'll go and publish the extensions to the Bower registry (they'll be available with the prefix "fluidtypo3-*").

> This is the revised version with the `version`, `main` and `ignore` properties removed.
