Two fixes from NuPogodi

1. ATM, the footers in selectmenu.lua & helppage.lua are left-adjusted,
these also contain the prompt for users how to call help
(selectmenu.lua) and how to go back (helppage.lua). By minor correction
to function DrawFooter() in filechooser.lua, one may readily make the
rest footers to look in a similar way.
2. When writing the code of inputbox.lua, I (NuPogodi) left the wrong
command to delete the 1st entry in the math function list
(called in calculator mode by pressing Alt-M).
