Rethink layout for home-page

We should rethink the layout for the dashboard/home-page.
There are some things that would be nice to display on the first page a user sees:

• Last 5-10 uploaded documents
• Documents marked with "special markers" (see Add special markers to document-schema #100 )
• Maybe the last edited documents (updateAt)
• Maybe "last login"
• Maybe "Text-recognition processes currently running, 5 of 15"
• Maybe the top 5 used tags
• Maybe the top 5 tags used in a search-query
• Maybe even more...
