(svn r15615) -Feature: show scenarios/heightmaps from both your home directory and installation directory.

-Change [FS#2692]: make it more likely that scenarios are saved to the directory where openttd.cfg is and not the installation directory (gives problems with e.g. Vista). The working directory still overrides the openttd.cfg directory though, but only if it has a scenario directory.
