Closes #182 (closed).
Problem:
In established applications with many models, there is no easy way to generate Administrate dashboards for some but not all of the models.
Solution:
Add a generator for creating only an Administrate dashboard manifest.
Users can edit the manifest file to add or remove models,
and then run rails g administrate:install
to generate only the dashboards listed in the manifest.
If the user runs rails g administrate:install
without first generating a manifest file,
Administrate will automatically create a manifest
and use it to guide the installation.
Small Changes:
Stub out Rails.root in generators during tests.
Using Rails.root lets us more accurately generate files
when the Rails app is not at the root of the repository,
such as in the example app.
