Bug fixes
Removed heroes spawning that don't exist in instant action. This should stop most unfinished modded heroes from spawning.

Update adding new mod options for disabling this mods custom icons and preventing heroes that you already own from spawning.

Updated to add a mod option for faction restrictions for all factions.

Credit to Tep11 for showing me a sensible way to get the contract spec for this to work.
