Long and float properties in custom components not appearing in scene builder

[chooxy]

Add support for long and float properties

Expected Behavior

Long and float properties appear in the properties tab.

Current Behavior

Long and float properties do not appear in the properties tab.

Context

This prevents developers from setting values for long/float properties in Scene Builder. Double can be used instead of float, but it's still an issue for long properties.

It is possible to set the values by editing the fxml file directly, but this requires developers to know and remember that the property exists in the first place, which is not ideal.
