Work out different queries for 'getting one value' and 'getting all values' #1

Now grlc supports dropdown lists for possible parameter values. Howerever, sometimes users don't want to specify one single value for these parameters, but all of them. This would imply mad-overkill query rewriting if done via parameters, so best solution is to write two types of queries:

One using parameters to fix one value
One using VALUES(?x IN (?v1, ... , ?vn)) to specify several (possibly all) values
