Handle relative urls for user

[aguingand]

set asset to '/' by default

config('app.asset_url')

Prevent dev to do the following for each route

route('home', absolute: false)

Implementation problem:

• laravel export crawler detect by default APP_URL as internal and skip all other urls, so if we put different base host the site is not crawled

Possible solution:

• set APP_URL to the final website url & start the crawling in from the local server url (127.0.1:8000) (the export LocalClient uses laravel kernel for each request not a real HTTP requesst)
