#3943 - System allow to create atoms with Charge value out or range

[DzhafarOFF]

How did you fix the issue?

Screenshots

Atom's charge out of allowed range

Atom's charge in allowed range

Please also review fix for corner case with zero charge defined explicitly:

Current behaviour

All zero charge values get displayed on canvas and explicitly shown in atom's property field but get removed after export anyway

Current.mov

Proposed behavaiour

All zero values don't get displayed on canvas and don't get shown in atom's property field. So there is no difference with default atom after explicitly setting zero as charge value.
