Updated and modified web elements for PlayerMarkers Minecraft plugin to work with the updated Minecraft Overviewer utility

This is a modified version of the PlayerMarkers Bukkit plugin.

The original plugin worked with older versions of Minecraft Overviewer which used the Google Maps Platform. Since an update, the project moved to Leaflet, thus the Minecraft plugin functionality broke.

This project contains and updated playermarkers.js file and a PHP script to get the corresponding Minecraft skin for players to show them on the Overviewer map.

The PHP script can get skin information from SkinRestorer plugin. This can be disabled. The PHP scripts uses GD library to create the avatar image used on the map.

There are bugs I know about. Probably will be fixed in the future.
