mcMMO Dashboard v1.23.0

- Bedrock skin support

Thanks to UUID stored by mcMMO we can easily know if a player is a bedrock player or not. If it is, then we use the TydiumAPI with his UUID to display his skin. Otherwise we still use player name to show his skin.

- Edit PHP scripts for skins (bedrock, uuid and name)

#UI changes:
- Better display for:
> best abilities in user page on small devices
> labels in user page on small devices
- Table in index page

#Bug fixes:
- title_header updated from "mcMMO Stats" to "mcMMO Dashboard"
