Progress: controller program and execute function improvements.

Progress: controller program and execute function improvements.

Get rid f fl_execute_parameter_option_fixated.
A better approach is just to allow a 0 to be passed instead of the string (aka: NULL).
The execute functions can then detect whether or not full fixation is needed.
An additional parameter check is now needed as if the program is 0 then there must be at least 1 argument defined.

Due to design changes the 'method' property for individual rule actions no longer needs to be on the rule action structure.
In fact, it is now confusing as each action represents only a single action (itself).

Add support for the "script" rule setting to designate the script program to run for scripts.

Add additional example entries and rules.
