This patch is split off from D3493, due to an unexplained checkrefs.pl complaint:
Loading maps XML... Wide character in subroutine entry at checkrefs.pl line 335.
This patch improves consistency in map descriptions of scenarios and skirmishes by making the following changes (per the style guide):
- → (one space instead of two)
- \u000a → \n (for consistency; identical)
- \" → “ or ” (proper quotation marks)
- fix a few typos
- don't capitalize cardinal directions (north, east, south, west), unless part of a name (e.g. Northern Europe, Far East, South Africa, Western Mediterranean)
- don't capitalize resources (food, wood, stone, metal)
Furthermore, three skirmish map descriptions mentioned Iberians didn't have starting walls. Those sentences are deleted, for consistency, since starting walls are actually absent on about half of all skirmish maps.
