AGAssert

Similar to NSAssert, but with slightly improved logging and is meant to ship with apps in release.

Benefits of using this over NSAssert:

• It is default on in all configurations since it uses AG_BLOCK_ASSERTIONS and not NS_BLOCK_ASSERTIONS.
• Slightly improved logging.
• Fewer macros and less mess.
• Does not require any description string as second parameter

The assert will raise an exception.
