Add page for uploading json files from tenor to configure persons and orgs

[ivarne]

Now you can open a separate tab on the localtest site and upload tenor kildedata to localtest internal storage. If there are relevant tenor files in storage, those will replace Ola Nordmann and Sofie Salt as the localtest users. You can also select a subset of the files to downoad testData.json to be used as app local users.

In addtition to the user management page, I have included the following changes.

• Cleanup of login page and use the menu on top instead of links scattered all over the login screen
• Use latest bootstrap (from CDN, per getboostrap.com instructions)
• Split HomeController into multiple smaller controllers.
• Move Reauthenticate button besides the login button and make it a less visible color.
• Loadbalancer redirects "/" and /Home/* to localtest, so all new controllers got a /Home/[controller]/[action] prefix
• use only spaces (not mixed with tabs) in nginx.conf.conf
