Fixed TileEntityEnderTank.hasCapability missing its side interact check. (Caused crashes with RFTools Liquid Monitor)
Changed when EnderTank data is loaded, saved, and unloaded.
Previously is was dependent on the Overworld (Dimension:0) but in rare cases when a mod/plugin unloaded or never loaded it, data issues could appear.
There shouldn't be any issues but I did change when/how the tank network loads/saves/unloads its data, and better safe then sorry.
So back up the endertanks folder in saves before updating.
