Split the big "homedecor" mod into multiple sub-mods

Any of these new submods can be run without any other
components that were once part of the big "homedecor"
mod, other than homedecor_common and homedecor_i18n

Reduced dependencies where possible, but each submod still
has its various dependencies more or less the same as before,
i.e. some need basic_materials, others need unifieddyes,
some need building_blocks, and so on.

All of the stuff that used to be under homedecor/handlers
got moved to homedecor_common, as did any models and/or textures
that are used by more than one other homedecor component.

All the miscellaneous items that didn't warrant their own
mod ended up in homedecor_misc, which can also be thought
of as the remains of the original "homedecor" mod, renamed.
