HIDE& SHOW objects from API

[Ali Ozdemir]

When user draws objects for one story, I would like to hide other stories. I would like to make objects visible/hidden with a function.

When you implement this feature please consider the following scenario: When I create object and send this object to openbrim, it renders everything again. If I hide object, I don't want to show this object when openbrim renders graphics window again. They need to be hidden.

As of 3.160309, there is now ObjectSetVisible() and ObjectGetVisible() methods to OBrIMConn object. You can use these method to set and get visibility of objects. Objects should retain visibility state between rendering, if you see otherwise, please create a separate issue for it.
