* Changed numeric check regex
- `^` may match the position right after a newline character, and `$` may match right before the newline character (due to the multiline flag being enabled by default), so substing these with `\A` and `\Z`.
- Changed both instances of `[0-9]` with the shorthand `\d`.
- Removed capturing group around the first `\d+`.
* Changed get character at index
`anyString[0, 1]` is functionally the same as `anyString[0]` because the range `[a, b]` returns all characters from index `a` up to but not including the char at index `b`.
* Fixed moves bounced back by Magic Coat/Bounced moves affecting Pokemon they normally shouldn't
* Fixed townmap compiler not saving any map names (doesn't make a difference; added for completionism)
* Update a few ruby utilities
* Fixed small typo bug in map renderer disposal
