Update front and about pages' text and images

Description

I think some text and images on the front and about pages are confusing (especially for the new users). It might create an illusion that they can get a professional support here. It also mentions Jive Software as fully involved here. The circular image also mentions "commercial extensions". Also "lead xmpp supporters" image is outdated (jive, google do not use xmpp anymore).

I think we should emphasize the voluntary nature of this community. I would remove those misleading images, editing them would be complex. Of course it would look less prettier without images
