Added some specs and refactored loading a bit
Made loader specs more independent of cards, doesn't need standard mods
Merge branch 'develop' into load_sets_and_specs
Also remove dirs argument and use the method that loads/accesses the class var

Conflicts:
	lib/wagn/loader.rb
Fix ups after merge
Remove *args on loading, move to application config
Forgot this, need to remove args where we call it too
minor cleanup of mod_dirs
resolved loader.rb conflict
