[PATCH] Add a few keys to unused combinations of us(altgr-intl)

[Paolo Bonzini]

Hi all,

this patch adds a couple of IMO desirable features to the us(altgr-intl) 
keymap.

First, the keymap does not have the dead-cedilla combination which is
useful to write Latvian characters such as ģ or ķ, as well as in 
Romanian ţ.  I placed it on AltGr+Shift+5 just because this combination 
was totally unused.

Second, the altgr-intl keymap says

// onequarter etc (not in iso8859-15) deleted to get three unshifted 
deadkeys:

but it is pointless to delete them -- you can just move them to fourth 
level instead, which is where this patch adds it.

Thanks,

Paolo
