Fix some Audax validator issues

I've run the validator and fixed few extra issues, game impacting ones are:
- Missing "Roman Revival" modifiers causing a CTD on displaying the tooltips for event ancrel.2152. They are restored from beta branch file roman_revival_modifiers.txt
- Y Mab Darogan event not firing due to bad trigger. Note: localized texts are missing.
- Missing wealth check on invite_druid_to_court decision (not found by the validator :p)
