Removed max_running_torque config functionality. Added check that allows the queue_driver's max_running property to be set via config.
Made method for setting and getting (one) generic options on queue_driver
Added ert_local.py to ignore list
Added a charptr max_running_string to the queue_driver struct, and moved some functions. Made helper functions static.
Changed the site config set_max_running functions to use the (new) queue_driver option support. The max_running value is still fetched with the old function, and not with the option system
Removed unused function set_string_option, and removed *_max_running from job_queue.h to avoid usage of it. Still loaded into python classes
Removed unused function to set current_driver
Rewrote the places where queue_driver_get and set_max_running was used, and replaced with option setting/getting. Removed set_max_running(int) and get from queue_driver header, to illustrate that we don't use it, but the python wrappers still wrapp'em. Should/could also be removed(later).
Corrected some noob mistakes
