Show instance details for support

[usul]

To help the community to give support, I recommend that there should be an easy way to export the basic informations of the current setup:

• build version (official release(?) and SVN versions)
• map infos (compile date and maptool version)
• (enabled plugins/features as graphics drivers, ...)

If all this informations are shown at one place (maybe the About-box or startup) it will make it very easy to endusers, to submit valid details that the support can rely on :)
