Implemented modular space ships. Remember that huge ship from default ships pack? Its model consumes 24 Mb of VRAM. Imagine a small fleet of (different) ships of such complexity...

It is obviously that this ship is built (with SHW 's editor) of few dozen modules. So what if we save in VRAM only these modules, and draw them many times according to "ship scheme". This is a modular ship approach. The result is pretty cool regarding to economy of memory. This (a bit updated) modular ship uses 3700 individual modules, but consumes only 1.7 Mb of VRAM, because there are only 20 different models of modules. And more, a huge fleet of ships build by SHW editor will consume only 1.7 Mb of VRAM!
