Enable webapp invite codes by default

This feature works pretty well and we should make it a default because most providers don't start with an open registration.

i can create a template for provider.json instead

@kwadronaut Please assign to him if you like.

For the record, we agreed that we need to document better the use of invite codes with the change to the default behaviour.

the new MR keeps the old behavior unless you are using the new leap_cli (not yet pushed to rubygems).

also, it adds a handy command 'leap run invite' to make it much easier to run through the initial setup process when invites are enabled.

I just installed a provider for the 34c3 platform workshop, and invite codes are disabled

I was QAing a default setup for a single-node VPN provider as shown in these slides.

Platform moved to float, webapp isn't really part of this setup anymore. Correct @micah ?
