App loader and minifying

There's actually an issue open to add some very basic minification here: https://github.com/espruino/BangleApps/i­ssues/3

Issue #3 so it's been going for a while. It's very high up my list so it should be done soon, but right now I spend a good 80% of my time answering emails so I'm not getting much time to enable it :(

I experienced problems with the settings.js file when using minification. My guess is that is because variable names are not consistent anymore between files. Could that be?

I don't think that should be it - not unless you used some really serious minification. Usually it only touches variable names when it's 100% sure they can be changed
