* Don't throw an error in the console when loading a try: URL
* Handle the possibility of compiling multiple scripts with the same filename, or multiple anonymous scripts
* Fix#4558: Much more robust caching of sources and source maps, more careful lookup of source maps especially for CoffeeScript code compiled within a Coffee script (. . . within a Coffee script, etc.)
* Reimplement `cake release` to just use the shell to avoid the issues plaguing that command (something to do with module caching perhaps)
