DDF-670 more minor improvements to the application ui.
more low hanging fruit.
added styles.css to .gitignore since its auto generated now.  We still want to keep the file though.
removed style.css from tracking so .gitignore would help.
added admin-modules-applications to the base features that are installed so we can use dev:watch on it.
Merge branch 'feature/DDF-670-v3' into develop
