(svn r3477) -Fix: a fix that fixed the last commit.. I shouldn't be committing here :)

(svn r3476) -Fix: fixed a warning from the OSX compiler, it is bogus, but oh well

(svn r3475) - Fix: you couldn't remove an item from a list-type of config ingame from the configuration file. Whatever you did, upon restart of OpenTTD those items were still there. To fix this we initialize the first item to NULL in SaveList as it is rebuilt anyways fully.

(svn r3474) -Fix: don't use CXXFLAGS for DEP and CFLAGS for Compile, gives funny results ;)

(svn r3473) - [PBS] forgot to delete pbs.[ch]

(svn r3472) - [PBS] Remove from trunk. Anyone interested can still find it in branch/pbs. This reverts revisions r3158, r3140, r3075, r2977, r2674, r2625, r2621, r2529, r2528, r2525, r2524, r2519, r2517, r2516, r2507, r2499. (in conjunction with Tron)
- The only change is that the nsignalsw.grf file is kept and that existing nightlies with PBS signals get those signals converted to combo-signals.

(svn r3470) - Fix: plug a memleak in _network_host_list.

(svn r3469) - Fix: plug a possible memleak with subsequential strdup's without freeing the previous value and make it possible to ban offline clients

(svn r3468) - Fix: Rail type availability should take climate type into account.

(svn r3467) - CodeChange: Remove an useless assignment (reads a value and just writes it back)" tree_cmd.c
