What does the mod do?

This mod periodically discards floor items at set (configurable) intervals and conveniently logs them, allowing the use of "/give" to retrieve them in case something important is deleted.
It also introduces Personalizing:
Combine an item with an Emerald Block (configurable) in an Anvil at the cost of 5 levels (configurable)
Marks an item's tooltip with "Property of DisplayName" (lang file).
Personalized items can be configured not to despawn naturally
Additionally, some relevant commands are added:
- - /mccleaner clean - Runs cleanup immediately and restarts the timer
  - /mccleaner clean_all - Runs cleanup immediately, cleans up personalized items too, and restarts the timer
  - /mccleaner reset - Resets the timer, skipping the next cleanup
Cleanup can be customized to have a list of items not to:
- Clean unless they have existed for a minimum amount of time (minimumLife)
- Discard (blacklistItemsCleaning)
- Log (blacklistItemsLogging)

When it comes to logging, clients will be given warning messages at set times (configurable) as such:

*Note that latest.log is a clickable link that will open the file if you have access to it.

While in the latest.log it will appear like this:

Each time a cleanup occurs, the log number in chat and the latest.log will increment, so that instead of referring to a time, players on servers can provide the log number instead.

The logging is also formatted in a way that you can simply copy and paste the info to use with the /give command
