New "tagged" logging system

[Sv443]

Instead of using a single log level number, a bit masked number should be used to store a set of "log tags" the user would like to allow being logged.
Each call to log, info, warn and error then needs to be given a specific tag, which if turned off in the config menu will reduce unnecessary info.
If the tags are added to the console identifier, this also has the advantage of way more powerful filtering in the console.
