Form validation for really large numbers

[Tristan Seligmann]

Axiom / SQLite can't handle integers above 9223372036854775807L; this places magnitude restrictions on any integer attributes, as well as attributes based on integers (such as the pointNdecimal family). This constraint isn't directly replicated in the view layer, thus resulting in unfriendly errors when trying to save a form with a value that is too large.
