Parse meta as 8 bit in Normal mode to fix the terminals using that

Browse Source 
The solution is a bit hackish, as we only consider the 8th bit to
mean alt in normal mode, because its unlikely accentuated characters
are going to be mapped there. It fixes using Alt on xterm, and
probably on iterm2 as well (not requiring the meta-sends-esc config
change anymore)
