Have a way to retrieve app url

[jaumard]

Trailpacks sometimes need to have access to the app url (for email url or url callbacks for example).

Maybe we can simply add a config.main.appUrl who is by default set to 'http://' + config.web.host + ':' + config.web.port and users can override it under main.js.

Like this trailpacks who need app url can always use config.main.appUrl instead of each one try to guess what it is...

Yea I think we could set this in config.web. There's no "standard" right now, but I think baseUrl makes sense. Various trailpacks already use hostname and port in config.web

Yeah I think it's better to avoid using host and port directly because how trailpack can detect SSL option ? Because host normally doesn't contains http(s). It will depends of the web server... If there a config.web.baseUrl user can set it with http/https if they want to.

Like this no problems with Trailpack that don't detect baseUrl correctly. Trails (or trailpack-core or each webserver trailpack ?) should set config.web.baseUrl to 'http://' + config.web.host + ':' + config.web.port by default.
