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.
Nope. This was debated at length in MVC5 and we decided you should use RegEx or a custom constraint if that's what you want. We felt the most common case by far is English `A-Z`.
