Revert "admin: add a tooltip for edit dashboard"

This reverts commit 925fde4cd471be5eae882aaed8e5067ef4a4bb7d.

The tooltip is incompatible with `bs-modal`!
receiver: add more logs about socket.io events to determine when it fails
logs: ability to log to a file
socketio: log last IP address of client
socketio: prefer x-forwarded-for address to log IP

This is not quite secure but most of the time, we are behind a proxy.
version: 2.0.2
db: add missing migration file
version: 2.0.3
grunt: also copy favicon
receiver: try to log exceptions in a meaningful way
admin: change font for display name in modal box
documentation: first version
