(MESS) gb.c: made softlist loading completely independent from internal cart header:

Browse Source 
now RAM size, Battery, RTC & Rumble purely rely on xml features. Updated xml accordingly. nw.

Also, notice that duplicated features (from these lists and from megadriv.xml) will be removed only after
0.148u1, so that people updating their lists but not the exe can still use the xml with their version which
requires them.
