Control whether actor is poisioned by resource through the use of upgrades.
Merge pull request #7038 from Mailaender/packaging-tweaks

Reduced the Travis dependencies and adapted the installation instructions
Add yaml-defined FMV playback to GUI elements
Update missions for yaml-defined FMV playback
Add video support to legacy map importer

This enables the map importer to map the .ini video definitions to ours.

The mapping is generally as follows:

Intro => BackgroundInfo
Brief => Briefing
Action => GameStart
Win => GameWon
Lose => GameLost

There are a couple of maps in Red Alert where Westwood assigned
a video that should probably be an Action video to the Intro field.
These occurences happen in the case where there is no Brief video,
without exception. I assume this is due to a limitation of the original
game code.
