Changeset 2685 for code/branches/buildsystem3/bin/orxonox_dev_build.keep_me

Fixed install target:

• log and config file go a to separate folder each
• The SignalHandler crash log is now "orxonox_crash.log" to avoid opening the file twice which might result in problems
• moved tcl scripts to media/tcl8.#/ as a temporary solution. I've also created a ticket to fix this.
• UPDATE YOUR MEDIA REPOSITORY
• orxonox.log pre-main gets written to either %TEMP% (windows) or /tmp (Unix) and when the path was set, the content is copied.
• removed Settings class and moved media path to Core
• media, log and config path are now all in Core where only the media path can be configured via ini file or command line
• Core::isDevBuild() tells whether we are running in the build or the installation directory (determined by the presence of "orxonox_dev_build.kepp_me" in the binary dir)
• renamed Settings::getDataPath to Core::getMediaPath
