Bump to 0.12.0: sam assert lib (very basic)

Use 'describe' to describe a particular suite, use 'expect' to
compare strings or ints, will print an error message and exit(1)
if it fails, do nothing otherwise. Prints 'Pass' after each
describe block works successfully.

Could be a lot more sophisticated, but better keep it simple,
since it's used to test rock itself :)
