(svn r2595) -Codechange: Introduced "IsSteepTileh" to find whether a tile is steep
(i.e. spans two height levels) and use it throughout the code.
-Codechange: Add CanBuildDepotByTileh to find if a tile is suitable to
build a depot on it. Wraps some bitmagic which seems quite unreadable at
first glance

(svn r2594) Fix: [strgen] Misc updates to the string system.
- Renamed the plural command to "P" instead of "PLURAL". Now write something like this to append an s on plural: {P "" s}. (You can optionally still add an argument index to explicitly specifiy which number that's used)
- Removed the pluralized cargo strings from the string files. The new method is to use the plural specifier {P}
- Added support for genders. First add "##gender der das die" on top, then use {G=der} on a cargoname/industry to set the gender, and to switch between genders do something like {G neu neu neue} {STRING}
- Updated the swedish/english translation with P strings.

(svn r2593) [Translators] Updated translations to 20050716 (27 lang(s))

(svn r2592) Feature: [strgen] New way to specify plural forms.
- {NUM} {PLURAL 0 car cars}: Prints either car or cars depending on if the argument 0 is plural.
Also supports languages with weird plural forms such as Polish.
The plural format needs to be specified in the beginning of the langfile, like "##plural 7" for Polish.
