Rnd fix

Fixes #6990

- Removes bluespace crystal construction from protolathe menu (as crystal was removed and caused runtimes)
- Adds notification when protolathe/imprinter construction fails, notifying user about this issue, giving them possibility to reset the console without losing research, and reminding them to post bug report.
Should be possible to simply make ````build_path```` into a non-string, same as how the Syndicate Uplink refers to orderable items.
This way we'll actually get compilation errors instead of runtime issues if the object in question cease to exist.
