(svn r6131) -Codechange : Complete all missing _ttdpatch_flags entries
-Feature : both unifiedmaglevmode are now set.
Maglev and monorail are not allowed to run on each other tracks and will not be.
Setting those flags will allow grfsets as the Norvegian one to be loaded
-Codechange : link the TTDPatch's irregularstations with OTTD's nonuniform_stations
-Codechange : Reformat the whole array (thanks Rubidium, it sure looks better now)
