add thunderbird 1, builds but exits(1)

thunderbird 1 is the last release without tabs, and not quite as bloated
as the newer ones - however it immediately exits after starting it.
someone may find the cause of it not working correcly - however enabling
debug mode currently causes a build error, so it's hard to track down.
