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() count variables, you are using $i in 2 nested for() loops, causing workers to endlessly spawn in some configurations.

Fixes a default ini setting pointing to a replaced composer dependency: The default fresque.ini file was still pointing to the default php-resque dependency, not your expanded php-resque-ex dependency

This pull request fixes both of these bugs.
