"Whatever" construct

WIP

Meant to allow by-passing type indication in some (common) cases, for instance:

.transform("age").using(_ + 1)

Instead of:

.transform(_.int("age")).using(_ + 1)

Technical notes

Issue with operations order

We do not support Byte, Short and Float in Whatever due to the fact that classes like Int.scala or Double.scala list overloaded operations in this order: Byte < Short < Char < Int < Long < Float < Double. For instance def *(x: Byte): Int comes before def *(x: Short): Int and so on. As a result some of the implicit conversions incorrectly choose to transform Whatever into Byte where Int should be chosen (and the value may not fit a Byte).
