Add an option to disable the automatic jump to the last post after replying

[mcwumbly (Dave McClure)]

Rather making it easier to prevent jumping on reply, I’m more in favor of making it easier to jump back to where you were, which would also be useful in other scenarios.

Some prior topics about that idea here:

• Remembered Topic location should be "First Unread" post instead of "Last Read" post
• Link to first unread post?
• Ability to Jump to First Unread post in Topic Navigator / Progress Bar
