Upgrade UI´s mapbox-gl library

[rmotitsuki]

Today, the mapbox-gl.js library is included in the index.html file as a script, in version v0.41.0.
It causes 2 problems:

• it is not maped by Node, and it is left out from the npm audit command
• The library is using and old key from previous developer

Mapbox shloud be upgraded to the latest version possible (current version is v3.4.0) to fix vulnerabilities issues.
To do that, a generic user must be created for amligh, to replace the token.

index.html - remove script
package.json - add "mapbox-gl" dependency
Map.vue - replace token
