changes main .bowerrc file to the non-bundled version

moves angular and other deps from the "devDependencies" -> "dependencies" section. This
has the consequence that the other deps (uri-templates, deep-diff) will be automatically fetched by bower when
installed by others.
This should solve issue #5.

The [Getting Started](https://github.com/phxdatasec/model-factory/wiki/Getting-Started) section of the wiki has to be updated. I'll do so once the PR is validated and merged.
