feature: options from commandline

[glensc]

i would like to build three similar .phar files, which differ only on entry point (and obviously) on output file.

i tried out of intuition like this:

$ box build -v --output git-hook.phar --main git-hook.php

  [RuntimeException]                     
  The "--output" option does not exist.  

which failed because no options supported in 2.4.4

I'll see that Box supports this in the next major version of Box.
