Candran 0.3.0

* Added @ self alias
* Added short anonymous functions declaration
* Made assignment operators works in every direction, except up, down,
behind and below, because this would be hard to visualize.
* Moved files around.
* Error rewriting.
* Discover the amazing can commandline tool, which includes a fantastic°
REPL and program running abilities.
* Added functions which plagiarize Lua.
* Added 0.1.0 to the version number.
* If you still love pineapple flavored bread, don't hesitate to show
your feelings.

Also, the tests are out of date. Sad.

°: not really.
