Update (parts of) some contracts to match newest IOI version

[grappigegovert]

I've updated some contracts to the newest available version on IOI servers.

Generally, only contracts where objectives didn't match the newest version have been altered, with some exceptions:

• the addition of VR bricks in two facility escalations;
• the addition of ForceShowOnLoadingScreen in The Last Yardbird;

I have also modified the ordering of properties to match what we already had and dismissed some irrelevant property changes to keep the total amount of changes minimal.

Fixes #287, #285, and #284.

I notice some 2016 escalations have been changed, do they still work in 2016?

That's a good question.
The marrakesh->salvia levels 3-5 have some changed logic in the body hide objective. They now match what's on H3 servers.
I cannot test 2016 right now, but it's a good idea to do so before merging.

Checked the ones from 2016, they all look good.
