(svn r2946) Remove redundant calls, simplify a check and terminate the argument list of execlp() as suggested by the manpage to make it correctly work on 64bit platforms

(svn r2945) Add 'del' alias to rm console command

(svn r2944) Add Revision keyword to the file for --version/-v

(svn r2943) Fix compilation of openttd in release mode. Don't use any precompiled headers, so no more troubles in the future.
Remove release build of strgen, since it is never used.
Add current ottd version to resource file. Don't forget to update when we make a release :)

(svn r2942) Staticise some functions

(svn r2941) -Feature: Implement the console command rm to remove savegames

(svn r2940) (Internal) Remove the need for the 'tmp' variable for _sl.buf, instead operate on _sl.buf_ori which is not changed for init/deinit.

(svn r2939) Fix racing condition when using threaded saving (last one I hope).
When game is saved and you save again you get an error message (not when autosaving) and it's aborted. When a game is loaded in the meanwhile execution pauses until saving thread finishes.

(svn r2938) -Fix: Exit the child of the extmidi backend with _exit() instead of exit(), because we don't want any atexit handlers - especially flushing output streams - to run, if exec() fails
Half a credit is due to Darkvater (;

(svn r2937) Add sprites for {, |, } and ~
