Allow integers to be given as inputs to fields that require floats

The score and quality fields in entity models are floats. Currently, zentity strictly requires the inputs of those fields to be floats. If an integer is submitted to one of these fields, zentity will throw a validation exception.

This behavior is too restrictive for some clients. JavaScript's JSON.stringify() serializer will force any number of 0.0 or 1.0 to be serialized as 0 or 1 and there is no easy way around this (cases: here, here).

zentity should allow integers as inputs to float fields, and then convert those fields to floats for its own purposes.

Merged into main: 5a45d41:

Allow integer values of 0 or 1 for the "score" and "quality" fields, which expect floating point numbers in the range of 0.0 - 1.0. Allow floating point numbers with zero decimal value (e.g. ###.0) for the "weight" field, which expects an integer value.
