Segfault when skipping ahead with EIA-708 closed captions enabled

Description

A segfault occasionally occurs when skipping ahead (with the right arrow key) while EIA-708 (ATSC) closed captions are turned on. I did some debugging with gdb, and discovered that the crash occurs in CC708Window::Scroll, which accesses the "text" variable even though it may be null. I've attached a patch which adds a null check to prevent this crash from occurring.
