Allow empty replacement strings in contrib/unaccent.
This is useful in languages where diacritic signs are represented as
separate characters; it's also one step towards letting unaccent be used
for arbitrary substring substitutions.
In passing, improve the user documentation for unaccent, which was sadly
vague about some important details.
