Add TikTok to limits, better default handling

The TrackerLimits.json now contains TikTok as well. Also if any tracker is missing from the json, a default limit is used instead of crashing.

Add update capability to setup scripts

By running sudo setup.sh update or setup.bat update the current container of mopsbot is getting updated to the latest release.

Better wait handling

Added commands to wait for mongodb to listen, instead of just waiting 5 seconds.

Added "verbose" command line argument to get all output, e.g. "setup.bat verbose"
Added "clean" command line argument to recreate the database, e.g. "./setup.sh clean"

Self-host scripts

The scripts and folder structure needed to self-host Mops.

Calling the .bat on Windows or .sh on Linux will take care of everything.
