Change Default Structure of Course Channels to Include Forms

[bladetyr]

Forms are currently utilized by CS1 courses as well as a few 200+ level courses. We should consider restructuring our default course channel set ups to be less bloated and include forms.

Completion of this issue should result in /addcourse creating these channels:

• #XYZ_general (text)
• #XYZ_staff (text, but private to staff as normal)
• #XYZ_labs (text)
• #XYZ_help (form)
• #XYZ_private_qs (text, but private to staff as normal)

It is important to note that this change would require changing any outstanding Canvas quizzes or Sage documentation.
