WIP: migrate components from phoenix
Move templates into the app namespace from the addon one
Expose all the components in the app namespace
Return in afterInstall method
Add blueprint
Allow blueprint command to be run without an additional param
Fix afterInstall callback
Import Spinner as an AMD module
Update paint dev dependency
Use Spinner global instead of AMD import

Reason: Importing the module made it available in the addon namespace but not in phoenix namespace.
Merge pull request #1 from alphasights/mde-migrate-components
