/bin and /disposal - same feature, 2 separate plugins

/bin appears to be a command in the Civilizations (Factions) plugin, but does not currently work. /disposal (and it's aliases, /trash, /edisposal, /etrash) are commands in the Essentials plugin, and DO work. It seems that only one of these should be enabled (either /bin, or /disposal) given that these are 2 different plugins with the same function. (at least if /bin gets fixed)
