Event keycodes for Android: 1073742094, 1073741942?

Hi all,

Been probing around a little so as to use the android “back” and "menu"
buttons for SDL applications. They appear to be, respectively, 1073742094
and 1073741942 - not sure what they correspond to in the enumeration
though: does anybody else? Would be nice to use the “real” macros in case
things are changed later on.
