[SoundComp-Develop] Wiki navigation sidebar, finally

[<js...@ya...>]

Dear SoundComp team,

finally I found the time to investigate the wiki a bit more. I never before noticed it is possible to replace the left navigation sidebar; now I found out and did so. It should be a bit easier to jump around now :-)

Still I haven't found a way to indent navigation items or otherwise bring level structure into the sidebar navigation in a better way, not even with explicit styles to each sidebar navigation item. Should anyone of you feel like a mediawiki expert, please replace the '- ' indentation of subitems by something more functional or better looking.

Best regards

Jan
