Embed BioDalliance (merged)

Definitely a little rough, but it works!

Highlights:
- This adds a notion of `selectedRecord` to VCFTable.
- I'm pulling a built version of dalliance from my github via NPM.
- This includes the `EventGuard` hack to prevent dalliance from stealing mousewheel events.
- BioDalliance is initialized lazily, since it's fairly expensive.
- I added a `VCFTable.scrollRecordToTop()` method -- not sure if this is the right way to do things!

UI is very much a work in progress, but wanted to get this out there:

This supercedes #78 

Better to use a fat-arrow and `this`, and then extract the target element from the event, rather than rely on JQuery dynamic rebinding of the target element. This way we're not polluting outside of the scope of the callback.
