[Give 2.0] Inline Documentation is confusing on the emails settings.

[Benunc]

Issue Overview

A change I made earlier which I thought was only displayed on individual forms is also displaying on the global settings.

Expected Behavior

Global settings should have different help text than per-form settings.

Current Behavior

That text should not show up there.

Possible Solution

Show global text like "Enable or disable for all forms. This setting can be overridden on individual forms."

Steps to Reproduce (for bugs)

1. On 2.0, navigate to Settings > Emails (tab)
2. click on any of the individual emails to edit
3. Just below enable/disable that text needs to be changed.
