Consolidate all the functions which parse lists of data. They're almost the same except for the data itself, so use templates.
As for the templated function which handles the list, boost the robustness by adding additional checking and error messages.
This system adds the code necessary for letting content creators specify
complex events by specifying a simple, program-like sequence of
operations that will be executed by the engine when a certain event is
triggered.
This PR provides modders with additional options to alter countermeasure values. Previously, countermeasures had a fixed, hardcoded fire wait time of 333 milliseconds, regardless of what `$Fire Wait:` was specified. Also, the AI would wait a fixed delay between firing of failed countermeasure launches and successful countermeasure launches. For successful launches the AI would double the fire wait. Also, Friendly ships would only use a fixed constant value for countermeasure firing chance, and not the value based on their class specific AI profile.
This PR exposes those values with the following options:
• Add main AI table flag: `Friendly Ships Use AI Profile Countermeasures Firing Chance`. This will allow Friendly ships to use their AI class profile countermeasure firing chance instead of the default fixed value from main AI table.
• Add value in CM section of weapons table: Countermeasures use fire wait time `+Use Fire Wait`. This is a boolean that allows the countermeasure’s fire wait to actually use what is specified in the `$Fire Wait:` section of that weapon.
• Add value in CM section weapons table: `+Fail Delay Equals Fire Wait`. The delay between failed countermeasure launches is set to use the fire wait value.
• Add value in CM section weapons table: `+Successful Launch Delay Multiplier`. This allows modders to set the value that is multiplied to fire wait for successful countermeasure launches.
