Simbrief Edit & Download Latest OFP (#1228)

* SimBrief OFP Edit

Changes aim to have ability of editing generated SimBrief Flight Plans and re-downloading.

* Move url to config

* Blade update and $uri change

* Update simbrief_form.blade.php

Used `$flight->id` along with `$user->ident` to have a more unique static id value. No details given for that fields uniqueness requirements, this will be ok I think though. 
Also we are passing user's simbrief userid with api to find the flight plan, both combined, no chance to get another users plan and/or any other plan of same user.

* Update SimBriefController.php

Move `static_id` to controller

* Update simbrief_form.blade.php

Read `static_id` from controller

* StyleFix

* Update phpvms.php

* Update SimBriefService.php
