Add a new submenu in the context menu for a text box. This submenu displays some spell check languages that Chrome supports, derived from the accept languages list and the current spell check language. The spell check language which is currently set is shown to be selected. The user can click on some other spell check language, and it will become effective immediately (this part of the code was addressed in a previous CL, and has been checked in).
