-Version information is no longer sent to logs during startup.
-Warning message for unopenable block being declared as openable now properly includes "FenceGateBlock" as class of blocks possible to open.
-Improved mod description.
-Blocks openable with key are now defined using "#irondoorkey:openable" tag, therefore they can now be added by other mods or datapacks (thanks to Anonyku05 for suggestion).
-Minor improvements.
