uber -V reports incorrect version

[dylanpyle]

(Following up from #20)

$ npm view uber-cli version
0.0.2

$ uber -V
0.0.1

Seems like the version is hardcoded here: https://github.com/jaebradley/uber-cli/blob/master/src/executables/uber.js#L5

@dylanpyle I'm thinking about just removing this flag entirely (mostly so that situations like this don't happen). Will be a breaking change, but I suspect user impact will be minimal. Any strong preferences one way or the other?

@jaebradley That's fine with me; I might consider something like #25 also though. Personally I'm a big fan of CLI utilities having --version flags that work.
