Stable Build 6314

New features for mappers:

• Add new triggerOnlyOnce option to Dialog Cutscene Triggers (true by default) that allows retriggering the cutscene without leaving and reentering the room if disabled (map editor support pending).
• Add new ignoreIntroState option to Dialog Cutscene Triggers that delays the cutscene until after the intro animation for triggers placed on spawnpoints (map editor support pending).

Tweaks:

• Make "Only Once" (now "No Respawn After Use") Dialog Cutscene Triggers not respawn at all once triggered instead of spawning but not functioning.
• Make main menu scrolling smooth.

Bugfixes:

• Clean up writing of modsettings to hopefully prevent modsettings files from being corrupted.
• Fall back to mirror when downloading mods after certain previously unhandled errors.
