Fix bugs that were reopened due to the change of setoid

implementation. Mostly syntax changes when declaring parametric
relations, but also some declarations were relying on "default"
relations on some carrier. Added a new DefaultRelation type class that
allows to do that, falling back to the last declared Equivalence
relation by default. This will be bound to Add Relation in the next
commit. 

Also, move the "left" and "right" notations in Program.Utils to "in_left" and
"in_right" to avoid clashes with existing scripts.

Minor change to record to allow choosing the name of the argument for
the record in projections to avoid possible incompatibilities.
