New global section template library

[ebruchez]

We currently have an orbeon library, which only contains a "US Address", which hasn't been updated in a long time. We should have a global library (see also #5495) with many reusable blocks, which could be used as is or as starting points.

Suggestions:

• addresses
  • new and improved "US Address"
  • "US Address" with autocompletion
  • "UK Address"
  • more addresses
• other
  • "Personal Information"
  • TODO
