[#881] Angular 6 (fixes #881)

[paulbert]

Note: Vagrantfile does not successfully update Node to 8.x. Need to run sudo apt upgrade from inside the VM to complete the upgrade.

Includes a lot of automatic changes from Angular and Rxjs upgrade scripts.

@sahilph @dogi @mappuji I had to remove the --arch flag from the ng build command in the crosscompile script. Angular was throwing an error & not running the build command otherwise.

Tested the build and it is still working on a Raspberry Pi, but let me know if we need that flag or something similar for the build command.

I don't know current updates for ng cli I assume it detects the architecture automatically in version 6. The thing we need to do is testing. Any special reason why previously we need to specify --arch @sahilph ?

Delete button on titlebar does not work. It gives undefined as meetup id. Delete on individual row works.

Layout of User list is broken. Also Add Team button does not work on each row. All other action including remove team works. Add Team on titlebar also works.
Add Team and Remove Team of individual row does not update.

Open profile of another user and edit it. Then profile icon on top header bar takes to profile of edited user. Homepage shows correct profile details.

All these issues seems to be on latest release itself so not related to angular except broken layout of users list view.
