This implements subtitleid and titleid properties for map annotations.
See JIRA ticket for a test case and instructions. Please test both runtimes (V8 and Rhino).
Enable subtitleid and titleid for Map Annotations.
Move locale property handling to KrollProxy.
Bill reviewing instead of Opie (so Opie can do one of mine)
CR/FR accepted. Tested 2.2 emulator and 3.1 device (T-Mobile G-Slate). Tested both rhino & v8. Also ran KS (just v8) for a sanity, and then drillbit "ui", "android.ui" and "locale" tests for kicks and laughs.
