Manual interventions:
• decorators on the same line for service and controller
injections and most computed property macros
• preserving import order when possible, both per-line
and intra-line
• moving new imports to the bottom
• removal of classic decorator for trivial cases
• conversion of init to constructor when appropriate
This is mostly deprecation fixes and blueprint changes. There
are some dependency updates too; the changes to Ember
Basic Dropdown necessitated changing it to angle bracket
component invocation. The conversion of the rest of the
templates will happen separately.
