space cannot be typed on us(hyena), us(miniguru) and us(yoda)

Circumvent #261 (closed)

NOTE: I lack sufficient knowledge at the moment for a proper fix.

IMPORTANT: Since the layouts hyena, miniguru and yoda at the moment are useless, because <SPCE> cannot be typed, the fix proposed here needs to be applied as soon as possible, even though (clearly!) the proper fix is work in progress.

I'm employing key <SPCE> { [ space, space, space, space, ... ] } at the moment, which I believe is wrong.

I don't think the fix proposed here is correct, since I don't think I should touch the first 4 definitions of <SPCE>. I mean, I should define it as [ NoSymbol, NoSymbol, NoSymbol, NoSymbol, ... ] instead of [ space, space, space, space, ... ] so that the involved layouts (which care about Level 5 only) would merge properly against some other requested layouts, without overwriting them.

Also, I'm observing some other issues which may or may not be related. A future fix should fix all these issues properly. Puzzling enough, as reported in #261 (closed), I only have trouble with installed files under /usr/share/X11/xkb; I don't have troubles when I employ the files under my working copy.
