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`
I know you like the *comment headers*, but I really don't think they are necessary.. Just by having an empty line between the variables is enough to tell that they are separate blocks (in case we have different kinds of variables). But we can keep doing it if you feel strong about it..
