Links to MapQuest terms broken in LICENSE.md

[ptandler]

Describe the bug
LICENSE.md contains http://developer.mapquest.com/web/info/terms-of-use and http://info.mapquest.com/terms-of-use/ as links to the MapQuest terms:

• the first is redirected to the homepage
• the last returns 403

Where was the bug observed
LICENSE.md, both server and client

Expected behavior
Well, find information about MapQuest terms 😏

Hi, can I dig into this and fix
where are those refs suppose to link to?

[andrew21-mch]

@Angamanga please will you mind checking this out, if those are not the link, you could please send my the right links to the terms and conditions
i also noticed there were two links listed in the LICENSE #4405

As I just mentioned in PR #4405 - does Ushahidi use MapQuest anymore? Maybe this should be updated to MapBox?

One thing that is very relevant for me any maybe also for other users: In legacy/app/app.js there is a mapbox key defined:

        MAPBOX_API_KEY:
            window.ushahidi.mapboxApiKey ||
            'pk.eyJ1IjoidXNoYWhpZGkiLCJhIjoiY2lxaXUzeHBvMDdndmZ0bmVmOWoyMzN6NiJ9.CX56ZmZJv0aUsxvH5huJBw', // Default OSS mapbox api key

It would be very helpful if the license would explain for which usages this key can be used. I would understand "default OSS mapbox api key" such that "as long as this is an open source software, one can use this key". But maybe there are some other relevant restrictions?
