Region condition wildcard support

Summary

Support wildcards on region condition.

This is a supplement for #959. Since this may be easier to achive, hope it can be implemented faster.

Usage

To support various region creating plugins such as ProtectionStone.

Value

Makes region condition more flexible.

Implementation

Add wildcards supports such as "?", "*" to region condition.

e.x.- region{r=ps*x*y*z} condition is able to detect region "ps0x0y0z", "ps100x64y-100z" and more.
