Assert module

For XPCShell tests and mochitests, Assert is already present as an instantiated global to which you can refer - you don't need to construct it yourself. You can immediately start using Assert.ok and similar methods as test assertions.

The full class documentation follows, but it is perhaps worth noting that this API is largely identical to NodeJS' assert module, with some omissions/changes including strict mode and string matching.
