Release 0.8

@jacobawenger adds 0.8 release of angularfire, upgrades seed to latest version of angular-seed, adds protractor tests, unit tests at 100%.

Probably the best way to review this will be to install it and see if it runs, try the unit tests, et al. Chat me if you need a primer or a high level discussion.

Fixes #40, #37, #30, #28, #26, #16, and #13
