This PR adds two properties (whose duals are already in the database):

  • being $\aleph_1$-cofiltered
  • having $\aleph_1$-cofiltered limits

This has been motivated by deciding some existing properties in the database. For the deduction system to properly work, properties should also always be dualized.

TODO: decide $\aleph_1$-cofiltered limits for all remaining categories (except for Sch)

  • FS
  • Ab_fg
  • FreeAb
  • Met
  • PMet
  • Sch
  • Man
  • Delta
