Move user.clj to dev profile, move init code from project.clj back to user.clj
Move app-template user.clj back to dev folder

making the project file closer to pure data (welcome being the exception.)
Add explicit dev fn to user.clj
Merge app changes
Finish refactoring dev
Merge #219
Correct merge typo
