Schema for new session-based container/asset stuff
Asset, session/slot, and permission/consent changes

Models and existing controllers updated.  Session controllers are still
necessary, which may take the form of updated Slot controllers that pull in all
session assets as well.
Readme updates for lisa
README: {Fix,mark}up
Add Slot.assets to get session assets, too

However, we've maybe decided to ditch the slot-container concept anyway...
Remove slot and rename session to slot

Yes, this is confusingly similar to reverting the recent commits, but slots are
now playing the role of sessions.
WIP: new attribute/measure schema; broken
Switch kind name fields to enums to be smaller and eliminate Checks
WIP: more comments and audit tables for annotations
Improved SQLArgs and Audit interface; annotations WIP broken
More functions for mapping annotations to targets

Also wrote a generic Asset.get.  All untested.
Minor bug fixes on comments and ranges.

Haven't I learned the val-val dependency problem by now?
Started writing scaladoc.

Not much yet, mostly making sure I understand the syntax.  Should figure out a
way to populate gh-pages with this, or some such.
av build: remove misinterpreted quotes

From mike, forgot to do this a while ago.
av build: hard-code include/linux for jni_md.h

If I can figure out how to properly determine the right name (os.name in
lowercase?) I can generalize this.
av.c: remove colorspace info newer than 2.0.1

And also hopefully unnecessary
Add gh-pages-doc task to sbt to automatically update apis on gh-pages branch

This only does the main project for the moment.  I have to figure out how to
run doc in and get a list of dependencies to fix that.
More models documentation and tweak Timeseries assets
Finish basic scaladoc coverage of models
Minor fixes; remove database name from default url

This makes it easier to change the database by changing the user.
