Log server

[sassanh]

Some issues can be easily resolved if the developer/user can access the logs and investigate them. Checking the logs on the small LCD of the device is a bit hard, it has value for cases when the device does not connect to any network though, but it's a limited use-case we can address later.
But most of the time, the device is already connected to a network, so we can run a log server over web socket. So the user open the log server (later integrated into the web dashboard), they see the tile of all the different log files and by clicking on these titles they can open that log content. If a new entry is added to that log, it will be immediately passed to the web client via the web socket and becomes visible to user.

Ideas for the future:

• log aggregation
• log filters (time range, fields, etc)
• export to file for archive
• connect to cloud/in-house archiving services
