Refactor the build system, decide on tools, etc

[rehno-lindeque]

At the moment we're using Cake for building, but this is a quick decision (it is easy to get started because I'm already familiar with cake and have templates to use)
Are there other build systems to use? For example, does http://npmjs.org/ allow us to do the same things as cake?

See also for example

• https://github.com/sstephenson/stitch for stitching together js files
• https://github.com/jrburke/requirejs for loading node modules (making debugging easier?)
• https://github.com/dannycoates/node-inspector/

And many other things to read

• Support for asynchronous loading (and not packing everything in one file) browserify/browserify#58
• line number mapping for debug jashkenas/coffeescript#558

Alternatively we may also use LangLang tools (https://github.com/LangLang/LangLang) for templating and building (perhaps through https://github.com/LangLang/bark)

Finally, what about a unit testing strategy? E.g.

• http://pivotal.github.com/jasmine/
• http://stackoverflow.com/questions/32809/javascript-unit-testing
• http://stackoverflow.com/questions/300855/looking-for-a-better-javascript-unit-test-tool

Also look at minification

• Currently using uglifyjs (which seems to work very nicely)
• Also look at the one used by jQuery (which I seem to remember is Java based, so probably no-no)
• Others?
