ShowItem 1.5.2 - Filter more item tags and add namespaced command option
Added more filtering of item stack NBT data in order to support items with lots of custom NBT data that isn't necessary to display the item hover message in chat. (This should solve most issues with item messages exceeding the maximum packet length)
Added the config option namespaced-commands to toggle whether or not the plugin name prefix is used for commands in the clickable inventory open chat messages. (Enabled by default as it makes sure that ShowItem's command is executed and not some other one)
