2 Bugs found with latest release

I recently upgraded from v0.1 to the latest 1.2 code and found a few bugs when trying to get my workers back up and running.

Fixes a bug with starting workers: There was a collision between for look variables, you were using $i in nested for loops, causing workers to endlessly spawn.

Fixes a default setting pointing to a no longer used composer dependency: the default fresque.ini file was still pointing to the default php-resque library, not your expanded php-resque-ex dependency

This pull request fixes both of these bugs.
