meta descriptions not working

[DaveSkender]

When trying to add HTML meta page descriptions, they do not showup. Found in #5 What we implemented:

• meta loaded in root module
• meta created and defined as a service in page constructors

Done when:

• [x] meta descriptions work
• [ ] sitemap.xml works for all routes
• [x] add URL in banner mention of GitHub repo
• [x] more meta icons
