Rip Ember.js from project

This is step 1 of replacing Ember.js with Angular.js. I'm sad
to see Ember go, but this is the way the cookie crumbles.
Initial Angular.js 'getting feet wet' commit
Show schedule list and details
Get lights and scenes from the server
Light status checks now driven by Angular controller

In addition, the general purpose JavaScript file 'hal.js' has been
replace with the Razberry Pi specific file 'razberry.js'.
Update light status intermittently
Provide link for cron documentation
Add garage camera partial
Update schedule details
Add /about/author server route

Yes, not strictly necessary, but why not? ;-)
You can now add schedules
Bump the version to 2014.04.24
