Github repo links in README.md should point to apache's account.
The only valid reference material we have is our Project's site.

Eventually, this could point to our Wiki, for one.

Before, it was the BB contributor forum, but since we are purely in ASF
(incubator), this generates some confusion, and points people to the
incorrect place (which is our mailing list).

Also, the doc/ reference link was removed as it is listed in
the website's content.
Remove git submodule support by changing how Jasmine is pulled in.

It is the only git submodule, that provides no extra benefit as one.
This also makes the project not depend on git to run tests.

Issue Ref: https://issues.apache.org/jira/browse/RIPPLE-13

Since the latest Jasmine stable release does not play well being in
NPM's package.json, it can be installed nicely with bower.
