Add Vietnames translation
Fixed the previously broken build.

Broken since e4493ee320ecb4c2d62a5ed6744497225eca0c24
This was because we weren't calling Localeapp#configure which apparently
is 100% required for Localeapp to not be calling LocaleApp.missing_translations#add when it is nil.

Also:
* Fixed localisation issues with forem.admin.groups
* Fixed testing against eql() to be_blank instead
* Fixed indentation in spec/helpers/formatting_helper_spec.rb and allowed it to run in isolation.
* Made spec order random
Stop allowing CI failure when running MRI 2.0.0
Application-less gems don't need a Gemfile.lock
Ignore the Gemfile.lock
Specify localeapp dependency and require it.

Fixes #414
Use rails g forem:install when generating dummy app.

This far more closely resembles what an actual application will receive.
Require absolute template paths.
Ensure that the specs running doesn't ruin the next spec run.
Fixes #416 by disabling Localeapp polling, sending and reloading in all environments.

You can override this in your application using your own initializer.
The forem initializer will run before those in RAILS_ROOT/config/initializers/*
