All Implemented Interfaces:
Checker, Updater
class PluginUpdateHandlerextends Object implements Checker, Updater
Check for or download an updated version of a plugin. A plugin is a standard .sud file with a 40-byte signature, a 16-byte version, and a .zip file.

So we get the current version and update URL for the installed plugin, then fetch the first 56 bytes of the URL, extract the version, and compare.

Moved from web/ and turned into an Updater.
