Removing cm_strings entails painful merging of upstream cm commits

and reduces the likelihood of cm's translation work being reflected in vanir... i think we should use (excluding strings for hings we don't have) bone-CM strings.xml and cm_strings.xml and add a vanir_strings for features cm doesn't have.

Revert "remove CM's proprietary strings.xml since there's only one string we need in it"

This reverts commit 188aed4c621152d8a4b55a026073895403285eec.
