EMC Shop locator

You can upload your sign database and download a common shared database now. The new configuration GUI allows you to enable or disable these options.

The plugin checks if it's connected to EMC now, and if it isn't, doesn't try to find shop signs.

Signs are saved (and uploaded) when disconnecting from EMC now, additionally to the "once in several minutes" schedule.

Signs that are gone are detected as missing and removed from the DB.

Item names that contain a ":", like "Potion:3", don't confuse the database any more.

Prices ending in "M" are supported now.

Much better handling of special items in CHOOSE chests:

•  Renamed standard items still use their standard name. If you rename your silk touch axe to "Melon Harvester", it's still shown in the "Diamond Axe" category in the shop finder.
• Renamed special items that have formatting in their item names are supposed to be special EMC items or promos, as normal players can't create these names, and are stored with their special names. So, searching for candy will find haunted candy and that Candy Cane sword.
• Renamed decoration heads are stored as "Deco Head - <name>". Searching for "Polaroid" will find that Polaroid camera in the /v +deco shop.
• Horses, Donkeys, Mules and Llamas have their stats appended to the category name if the stats are "interesting" - search for Horse and find "Spawn Horse (Spd=132) now!

As this is the first version that synchronizes signs over the internet, and I don't want an accidentially messed up central database mess up your local one, downloading is disabled per default and you need to enable it in the options.
