Description

Add option to rename tabs to context menu. (Tab ReTitle implements this feature.)

Rationale
If a user has many tabs from the same website, it can be difficult to identify the tab he needs, especially if the tab titles are cut off or are not very descriptive. For instance, I use Westlaw to do legal research. By default, it can be difficult to keep track of Westlaw tabs.

After renaming the tabs, it is much easier.

However, to do that currently I have to use a different add-on and navigate to the tab before renaming it.
