Bring back color changer for MIUI-like carrier label (no conflicts with DCC)

This was taken out when we implemented Yanuar/Omni's DCC here
https://github.com/DirtyUnicorns-KitKat/packages_apps_Settings/commit/22fe49b14f0d4698100e237940a4916555f36689

With this commit, the color changer for MIUI-like carrier label will be disabled whenever
DCC is enabled and vice versa.

Original credit/thanks to the author of the MIUI carrier color changer for that.

- Disable color changer for Clock and Traffic indicator as well
- Remove action bar reset
