Inline constraints

This one contains all the remaining constraints except the Regex constraint which is not registered to work as inline constraint. I will add it as a separate commit/PR, it needs special handling as it depends on the behavior of not splitting the parameters on a comma. ( The code we had would not work as today we have two constructors for RegexConstraint)..More on this in the PR.
This causes a problem with inline constraints because we now have two constructors (which aren't there in previous inline constraints). We can work on that in the next PR though
