Team Maps Expansion: New team spawnzones for multiple maps (#4058)

## Description:

Lets give Teams and HvN gamemodes some attention. Adds team spawnzones
to the following maps, and boosts them to appear more frequently as this
gamemode:

- Straitofgibraltar - 2 teams
- Aegean - 2 teams
- Beringsea - 2 teams
- Beringstrait - 2 teams
- Bosphorusstraits - 2 teams
- Conakry - 2 teams
- Falklandislands - 2 teams
- Straitofhormuz - 2 teams
- Tradersdream - 2 teams
- Surrounded - 2 teams & 4 teams
- Pluto - 2 teams
- Gulf of St. Lawrence - 3 teams

These maps (especially the ones for 2 teams) are all very symmetrical
and would be nice gift for the playerbase, which enjoys these kind of
games like FourIslands4Teams and Baikal2Teams. This is also nice for
HvN, as it centralizes the players and gives them a better chance at
defeating the nations.
