Option to hide tutorial/recitation slots for specific and all modules

[charleslimjh]

Is your feature request related to a problem? Please describe.

Random tutorial slot is selected when a module is added to the timetable. Ends up looking very cluttered. Would like to visualize timetable before tutorial/recitation bidding occurs.

Describe the solution you'd like

May consider a button/feature to hide tutorial and recitation slots for individual/all mods.
