Crusader Kings III modding language support in Atom

Adds syntax highlighting to Crusader Kings III config files in Atom.

Highlighting support for the following

• Event files
• On_action files
• Scripted effect files with highlighting of effects when named *_effect (e.g. increase_incest_effect = yes)
• Scripted trigger files with highlighting of triggers when named *_trigger (e.g. is_secret_karling_trigger = yes)
• Most history configs except offmap_powers and provinces
• The Validator commands (e.g. # Audax Validator "." Ignore_ALL)
• Highlights event_targets
• And more!

Contributions are greatly appreciated.
