Bug 1027707 - Replace the existing module loading facilities in calendar r=millermedeiros

### Change Summary

+ Move default configuration in build into separate json configuration file
+ Only load `main.js` in `index.html`
+ Get rid of lots of app-specific globals from `.jshintrc`
+ Turn all js files (except for `main.js`, `caldav_worker.js`, `test/unit/setup.js`, and some stuff in `ext/`) into amd modules
+ require `alameda.js@0.2.0` in `package.json`
+ No more `LazyLoader`, `LoadConfig`, and `NotAmd`
it's weird that in some places it's doing `new mutations.create` and here it doesn't have the `new`..

PS: `mutations.create` should probably be a function, not a class. - we only instantiate it to call `commit`, so `commit` should probably receive the `options` as first argument.
