DATAREST-665 - Switched to a more consistent scheme for I18N of JsonSchema.

We now use the following keys in the resource bundle to determine values for the title attribute of JSON schema property (in descending order of preference):

$fullyQualifiedClassName.$property._title
$simpleClassName.$property._title
$property._title

Also tweaked JsonProperty.format to make sure it always serializes as its toString() value.
