Bug 21589105 Rescope WRITE_SETTINGS (UX and Settings app change)...

Overall, fixed the detection of the state of permission in the corresponding
UX to be more accurate. Also ensured that apps needing this capability can
launch the summary UX through a specific intent.

AndroidManifest:
Adds the proper intent-filter so that apps can launch the Settings page using
intent.

strings.xml:
Increased the CHAR limits for some strings due to requests from translators.
