Have Latin IME re-capitalize a selected string
Upon pressing Shift, if there is currently a selected string, have Latin IME change its capitalization. This does not yet have the keyboard mode follow the mode - the change is complicated enough as is. Bug: 7657025 Change-Id: I54fe8485f44e04efd72c71ac9feee5ce21ba06f2main
