Attempt to build travis in stages

Hopefully this will lead to overall faster builds

Also:
- try to allow failures
- Version-specific vo caches
- Make archives stage-specific

This way, if multiple branches are running stages at the same time, they
don't have as much a chance of clobbering each others builds.
