run init over web and rework tools view

[foxbow]

initializing the mixplay configuration is done via the command line. This process should be moved to the browser for headless installations.

This may also be used to add new remotes on a running system. However the maintenance access should be password locked. Like setting the password on the very first access, initialize the basic system and run. After that, changes to the config (QUIT, flirc-support, change music directory, add profile, rescan) should only be accessible after giving the password.

Adding profiles and channels are borderline issues.
