Cleanup and fixes to mesh_discombobulator

Run Flake8 on __init__ and mesh_discombobulator
Clean up the bl_info (the scipt is now a module)
Moved the discombobulator props to a separate property group
Removed the duplicate entries of props in the script
Added poll functions for discombobulator operators
Used a prop_dialog instead of popup
Moved the execution operator from draw to execute
Added a remove all doodads option
Moved the list of doodads from the label to a separate menu
Expanded on Usage Information to cover more limitations
and changed it to a menu
Limit the repeat protusions to 4 instead of 10
(There is no RAM and CPU big enough in the world
to take all in the hubris of unrealistic ambitions)
