GTK2: add crude "import backup" dialog to File menu 

this is necessary to load saves from other devices or emulators,
as desmume uses its own incompatible format.

it works for importing .sav files from flashcarts, but only if the
file extension is .sav or .SAV - if using .dsv desmume guesses it's
of its own type and looks for a specific string, then fails.

the right code was taken from windows/importSave.cpp - it might make
sense to add the export item at some point too, however that will
probably require some more effort.
