(svn r5) -Fix: townname generation of TTDLX savegames. All work

Browse Source 
except for German Townnames (also fix one typo on 
English town-names)
-CodeChange: *act_paper to *act_water in Town to 
more resemble its use
-Fix: AI players now retain AI status. Since TTDLX 
savegame status is not fully documented, some holes 
exist (AI state is set to one without a vehicle, otherwise 
it crashes)
