Added creating gzipped file to the build process
A lot of stuff

* Added strict mode
* Fixed a bug when getting module exports (Falsy values of module
exports didn't work before)
* Updated script loader: Asynchronous if possible, full script path (IE
compability)
* The factory of a module definition can now be an object, if no
dependencies have been defined (Compability to AMD spec)

application
* Added some standard spec functions (it's incomplete now)
