Move repoindex projects, with history, into the bnd repo

The repoindex projects are moved into the bnd repo. The projects, with their history, were "extracted" from the bindex repo by filtering out the other files/folders.

`git filter-branch --prune-empty --tree-filter 'rm -rf $(find . -depth 1 -not -name "org.osgi.impl.bundle.*")' HEAD`

This modified branch was then pulled into the bnd repo and merged with master: ff46e3042dd858cdfbc1759341d62f78e8d02d98.

The remainder of this pull request fixes up the projects to build in the bnd build and modifies the build to use the newly built repoindex to index the release repo.
