Added StaticSupportTrait for blocks which require unconditional support
dynamic support requirements, such as those presented by item frames and torches, are not included.
in addition, double blocks, such as tallgrass, small dripleaf and doors, do not cooperate well with this, so they are also not included.
some blocks which could be migrated (such as chorus plant) were skipped due to unresolved problems.
this needs to be dealt with before release otherwise we'll be stuck with FortuneDropHelper::grass()
this is the obvious solution and should have been done some time ago - stuff like flammability was already a problem for double tall grass anyway
