initial command line utility for running a stage of actors

[sphaero]

includes new utility class sph_stage for managing a stage and sph_stock containing stock actors (Log, Pulse, Count)

CLI utility is called sph:

$ ./sph
sph [options] <config file>
  --verbose / -v         verbose output
  --help / -h            this information
  <config file>          stage config file to load

Example run:

$ ./sph test.gzs

stage_save still has to return an int (no idea why unix allows this (probably a default return?), but won't compile on windows like this)

[sphaero]

Yes, missed that one.It's actually the compiler (gcc) that allows it. Clang probably does the same as OSX compiles fine as well.

[sphaero]

It's passing now
