Description

Add ways for users to access Trace's documentation and EED Software Application's feedback form. The URLs for these forms can be changed in the config file for Trace: trace/config.json. The key for the URL for the docs page is "documentation_url", and for the feedback form it is "feedback_form_url".

These sites are accessible via buttons above the plot section as well as menu actions in a new "Help" menu. A warning window is opened if the link is not opened correctly. The window shows the URL so users can reference it manually.

Motivation

Users should have an easily accessible way to submit feedback on the application as well as a way of finding help if they have any questions.
