Fixes docopt#32. This makes 3 main changes to this library's behavior: 1) `pUsagePatterns` (and thus `pDocopt`) parses out the "Usage:" section of the helpstring as a string and returns that. The way I'm parsing it feels really hacky but I wasn't sure a better way to achieve it. 2) `exitWithUsage` and `exitWithUsaegMessage` now print that "short usage string" rather than the whole helpstring. `exitWithHelpstring` has been added, which prints the whole helpstring. 3) `parseArgsOrExit` automatically exits printing the helpstring if `longOption "help"` is present, to be more consistent with the original `docopt` behavior. I'm not sure this is the correct place in the library to put it, but it creates the intended behavior.
