patch

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.

Also, when I was looking at the keymap I noticed this:

// 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.
