Show overflow from allies
Updated changelog storage/overflow
Show storage information in team

* There's now storage information in score overlay
* Show in score if someone is ally / foe (red / green)
* Refactored the code to use own economy sync function
Show overflow of allies in score

It does this by switching value between storage / overflow when storage is 100%
Fixed bugs with showing overflow and replays
New UI-option: Team economy
Team economy off by default
Remove 'Xngine' strings.
Fix catastrophic indentation issues in trueskill.lua

Closes #224
Fix custom backgrounds in skirmish/LAN.

Fixes #225
Disable collision on sinking air wrecks

Air wrecks were colliding will other units, sometimes causing them to get
stuck in naval units.

This resulted in scouts having intel so long as they didn't sink to
sea-bottom and get wrecked

Fixes #194, closes #222
Work with colossus

* An additional death animation
* Death weapon now using the generic codepath in sim/Unit.lua

On a side note, the way death weapons work at the moment are silly, if
you're staying 4.1 from the unit 0 damage, 4 - 7500 damage.

I will send in a gradient damage patch to make damage variable depending
on distance from centrum
table.binsert

Binary insert into table to skip the need of sorting the table afterwards
New GPG-file: lua/sim/DefaultDamage.lua
Fixed linting errors
