Bumped version to 0.3.2
Wall Factory:
Fix crash with Wall Factory when openings and slots
are enabled (unorderable types: opening() < opening())
with the repeat option on as the sort function compared
stored classes instead of the numerical values
Fix the module not working properly after (F8) reload
Cleanup - consistent prop definitions
Remove star imports
Small UI reorganization to save vertical space
The code will probably need some further refactor
as the usage of globals is not so clear

add_mesh_triangles:
cleanup, remove unused vars add missing GPL notice,
some UI tweaks, add tooltip

add_mesh_pyramid: indentation cleanup
add_mesh_beam_builder: add an option to snap to cursor
add_mesh_teapot: use defs instead of assigning lambdas (E731)
