* photoid.c: Provide default image viewer for Win32.

* misc.c (pct_expando): %t means extension, not name ("jpg", not "jpeg").

* keyserver.c (keyserver_spawn), photoid.c (show_photos), exec.h, exec.c:
Allow the caller to determine the temp file extension when starting an
exec_write and change all callers.
