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`
just a note (don't need to change it): I usually favor `exports` over `module.exports` (`module.exports` is kind of a hack and only needed when you need to define something that isn't a plain object). but I agree that the amount of changes is smaller so I'm OK with it for now.
