Revamp Community Website

[kahboom]

We need to make some pretty big changes to the website, which include, but is not limited to, the following:

• Merge Developer Handbook page with community website, synchronize CD/CI pipeline (Incorporate Developer Handbook & community site #88)
• Improve/update information and documentation (Improve/update information and documentation #97 )
• Create CI job for deploying User docs to Syndesis website (CI job to deploy User docs to Syndesis website #99)
• Update screenshots on landing page & others (Update screenshots on landing page & others #94 )
• Update Google Analytics to include important dates (public presentations, etc)
• Discuss possibility of removing the website blog, or replacing with a News/Announcements page (Discuss possibility of removing blog #93 )
• Improve appearance (update octocat (Update Octocat color to match rest of the site #45), improve mobile compatibility and desktop styling, etc) (Improve appearance & mobile compatibility #96 )
• Update logo and favicon (Update logo & favicon #113)
• Include reference repos like Kurt's quickstart examples (cc @KurtStam )

EDIT: Moving SEO updates and improvements (#95 ) to its own epic, as it is quite entailed.
