Added support for PlotSquared v5 (in addition to v3 and v4). Thanks, @xTronix, for the bug report!
The update-checker will no longer read the hash of the file if it's not needed; it only reads it right before downloading the latest update now. Thanks, @SlimeDog, for the report!
Fixed fast doors (e.g. very small ones) getting toggled twice by the same button. Thanks, @Wolf2323, for the bug report!
