(svn r3555) -Codechange: [Big Endian] removed defining OTTD_ALIGNMENT by default on Big Endian CPUs
this increased speed when reading unaligned data (like strings)
test showed this to increase speed by 5,6% when drawing the mini map on PPC OSX

the tradeoff is that now it will crash if a Big Endian computer don't support unaligned reading
but it should easily fixable in stdafx.h if it turns out to be a problem
