3.5.7-alpha

- better reporting of configuration errors (instead of disabling the plugin, send the error on startup and whenever a command is executed)
- don't check for updates if on a pre-release version
- add infinite rankup loop detection
- add itemh requirement (like the item requirement, but not deductible)
- make it so i only have to change the plugin version in one place
