This implements right-to-left message automatic detection support in the compose box as well as the message feed. Full unit tests and support in the message-editing UI are for future work (as are potentially more fancy things like supporting things like right-to-left multi-word names for users/streams/etc.). Fixes #3123.

Our tools want to be able to identify which modules
|
|
add which HTML/CSS classes, and we need two things to
|
|
happen:
|
|
|
|
- The code must explicitly name the class.
|
|
- Only one module can refer to that class (unless
|
|
it is something generic like an alert class).
|
|
|
|
If you get this error, you can usually address it by
|
|
refactoring your code to be more explicit, or you can
|
|
move the common code that sets the class to a library
|
|
module. If neither of those applies, you need to
|
|
modify %s
