Title: Add U2211 (mathematical sum). Move sumint to sint.

Add

for the mathematical symbol
n-ary sum. Needed to move ··sumint to ··sint to make room. But I think
it fits with ··gint.

I know there is a certain overlap with Greek capital sigma. I think it can’t hurt to have both and have sum available under a mnemonic name.
