Allow customization of number of visible lines in a collapsed status

[neatchee]

Pitch

Add a customization option in Glitch settings to control how many lines are visible for a collapsed status
Allows users to control how visible a collapsed status is (i.e. fully collapse to minimum size vs just truncate at the collapse trigger length)

Motivation

When the collapse feature is enabled, it can decrease visibility of the those statuses. It has been conveyed that collapsed statuses are naturally ignored because there simply isn't enough content to motivate a user to expand and read the post

It looks like I'll need to look at the back-end code and learn some RoR for this one, but @neatchee, are the user settings (like advanced web interface, slow mode, etc.) stored in with the user's credentials (user name, email, and password), or are they stored in a different table and connected with a "has-one" relationship? Depending on where the user settings are stored, I could write an Active Record model and migration for this feature. I then can dig into some react code and get the new settings and implement them in the relevant component.
