Rename OUStringLiteral1 to OUStringChar

It started out as a wrapper around character literals, but has by now become a
wrapper around arbitrary single characters.  Besides updating the documentation,
this change is a mechanical

for i in $(git grep -Fl OUStringLiteral1); do sed -i -e s/OUStringLiteral1/OUStringChar/g "$i"; done
