AI 150370: Add localized content infrastructure in droiddoc templates, javascript, and css. DocFile.java - instead of FileReader, use InputStreamReader with UTF-8 encoding. ClearPage.java - add UTF-8 output encoding to FileOutputStreamWriter. Note: this change also up-integrates gerrit 2146 (smain).
