Added new items for 1.4.6

Fix permission for other help command (why are there two?)
- Made registerhelp read from yaml (not that the setting does anything)
Added an option to override data value limits.
- This should fix some mods which use data values above 16
- May cause issues if set to true and people mess with vanilla data values
