Public-facing user home page redesign

When you click on someone's webid, wherever you click on a link to them in the solid world, they will want you to see a profile display which does them credit and represents them well on the web. This is quite different from the private home screen which is covered in https://github.com/solid/node-solid-server/issues/889.
What sort of things?

• Photo(s)

• Customizable style, color, etc, background images, etc

• Contact details which are public.

• Statement like twitter profile

• Timeline of public things posts, etc

Optionally a selection of:

• Professional role, status, CVS a la linked in
• My public folder
• My public photos, music, video clips.
• Publications, blogs, papers,
• List of my public social graph (friends list)
• etc

but also things which as a viewer

Interact to me:

• Message me
• mail me
• Invite me to things.

If viewer not logged on, allow to log on.

If viewer logged on, possibly give more things, but pulling data from ACL's files like a friends-only timeline, indexes, etc.

Bắt đầu bằng việc xem xét issue 889 để tách màn hình chính riêng tư khỏi hồ sơ công khai này. Issue liệt kê nhiều tính năng hồ sơ, xã hội, phương tiện và tương tác tùy chọn nhưng không nêu tệp hoặc bài kiểm thử nào; cần thống nhất về phạm vi và tiêu chí nghiệm thu trước khi có thể coi việc triển khai là hoàn tất.
