Small graphical patch fixing some snow craters and scorch marks

Three new 5-player RA maps:

- The White Pentagon - snow based land/water map with minimal obstructions.
- Black Gold - Resource starved map with each starting position receiving 8 oil derricks.
- Texas Sea - Similar to Black Gold, but every starting position is on a tiny island.
make Volkov a true Cyborg

- Added new Armor value: Cybernetic
- Use sounds/graphics from DE censored version
- Heals near repair pad (instead of hospital)
- Medic can't heal him
- Dogs can't eat him
- Tanks need to attempts to crush him
- +25% HP (now same factor as 4tnk:1tnk compared to e1)
add @Generalcamo to AUTHORS

original Volkov contribution came from

Fixed airfield name.

The name of the airfield was airstrip... which is wrong since the icon says airfield whilte the building is called airstrip... its even called AFLD in the code so... just a simple fix :)
don't hardcode custom prerequisites anymore

to make those strings translatable
expose strings from build palette widget to chrome yaml

prepare for localisation efforts
customisable text printed on RA support power icons
customisable Ready/Hold text for CnC mod

make those strings also translatable
Fixed repairing landed airplanes (most likely #2365)

When an airplane was landed and ordered to another airstrip or service depot, the aproach distance was not properly calculated since it was not taken into effect that its current altitude is zero.
Changed scroll velocity in the map chooser to be better suited for mouse scrolling
