global bio4j reorg

I'm putting this here I don't know why. This is just the director's cut from ohnosequences/bio4j-paper#25

# bio4j changes

## github org repo layout

- [x] bio4j/bio4j ↦ the abstract model, incorporating the contents of what is now called **bio4j-model**. Also generic docs will go there; it will act as some sort of hub for the whole bio4j experience :)
- [x] bio4j/bio4j-titandb
- [x] bio4j/bio4j-neo4jdb
- [x] ohnosequences/bio4j-paper ↦ bio4j/???-paper once we submit it
- [x] ohnosequences/bio4j-scala ↦ bio4j/bio4j-modules
- [x] bio4j/bio4j.github.com
- [x] bio4j/Bio4jModel ↦ bio4j/DEPRECATED Bio4jModel and we add a link to the main bio4j/bio4j repo.
- [x] bio4j/Bio4jTools ↦ bio4j/examples
- [x] all the other stuff: add a big DEPRECATED to the name, link to the main repo.

## todo

### development and release process

Integrate all development into the standard sbt-based workflow. This means

- [x] using the release plugin
- [ ] writing proper release notes for the initial release (and keep doing it further on)
- [ ] fix those lingering "sbt stuff on windows" issues

### docs

- [ ] move things out of the wiki, into the main repository. 
- [ ] All docs should be included with repos, and correspond to the current branch
- [ ] update the website
- [x] add the new slides somewhere
