Merge branch 'master' of github.com:bvandenbos/resque-scheduler
Updating readme to call out dynamic schedules only being available in 2.0.0
Allow dynamic to be set by an environment variable so the entire
environment doesn't have to be loaded to have the scheduler be dynamic.

Some other fixes:
- Allow USR1 to print out the rufus scheduler for debugging
- Load the schedules during load (this may have been fixed in another
  commit)
