Fix more bugs, move plugins.edn and add enabled

- Move plugins.edn to config/ as it is user configuration
- Add plugin-config enabled flag and moved plugin enabled
- Fixed bugs with manual install
- Refactored plugin-config component to have its own listener
- Split out shared plugin fns to a common ns - plugin-config shouldn't
  need to depend on a component like plugin-handler
- Bump rewrite-edn to include upstream fix and avoid tons of cljs
  warnings with earlier versions
- Fix react warning introduced outside this PR in ui/icon
