Dev:Register replaceable module

Replaceable Module allow you replace QuickShop some part of code with yours.

Register

All works must done before QuickShop onEnable() called. So you must do like that:

1. Add depend into plugin.yml make sure QuickShop loaded before your plugin loaded.

softdepend: [QuickShop]

2. Impl the interface.
3. Register your module into quickshop, quickshop use services manager so you need register yourself classes to services manager before quickshop booted up.

publicvoidonLoad(){ //MUST ON ONLOAD METHODItemMatchermathcer = newYourSelfMatcher();
Bukkit.getServicesManager().register(mathcer, ItemMatcher.class, this, ServicePriority.NORMAL);
}

And we done, quickshop will use your module as expected.
