Mantis #3127: fix the spatial check in the rewritten algorithm

Fix a crash reported by Axem related to freeing the dock list of an object. This was caused by freeing the dock list from the destructor of an object which meant that copies of an object would corrupt the original object instance. To make sure that doesn't happen again the copy constructor and assignment operator of object have been made private.

gr_opengl_string retooled to use glDrawArrays. Should be a bit faster now.

Minor followup to r11150.

The regular parsing code not using the same broken logic as parse_comments() is not the same thing as it "ignoring" too high versions, and searching for repetitions of the same token would result in just finding the first one over and over again (the likelihood of this actually mattering to anyone is minuscule, but I needed something to test commit access, and this code has been tested).
