EVWHS Fix / Auth Prompt

[pjdufour]

The default auth prompt logic for WMS servers is hardcoded for GeoServer. See https://github.com/ROGUE-JCTD/MapLoom/blob/master/src/common/addlayers/AddServerDirective.js#L107. This prevents WMS servers such as https://rdog.digitalglobe.com/mapservice/wmsaccess?connectid=XXX-XXX-XXX from authenticating properly.

EVWHS will authenticate properly when using server.url (the original url). Can we just hit the original WMS endpoint instead of /rest/settings.json' for all WMS servers?

Also need to change:

serverAuthenticationUrl = serverAuthenticationUrl.replace('http://', 'http://null:null@');

serverAuthenticationUrl = serverAuthenticationUrl.replace('http://', 'http://null:null@').replace('https://', 'https://null:null@');

or use some advanced regex.

Hotfix

 var serverAuthenticationUrl = server.url.startsWith('https://rdog.digitalglobe.com/') ? server.url : (serverBaseUrl + '/rest/settings.json');
