Fix silly-sounding names

While I agree with the capitalization changes that Zefram made, I don't think that the item name is the place to describe the function of a device.

Also, calling something, for example, an "Accelerating Pneumatic Tube Segment" makes it sound like the tube segment itself is accelerating. "Accelerator Pneumatic Tube Segment" is a better way to word it, as that makes it sound more like it is a device used for accelerating (which it is). This is also why the right-side pedal on a car is called the "Accelerator Pedal", and not the "Accelerating Pedal".

For those filters, it also is (I think) better to call them "Mese Filters" than "Stackwise Filters". Sure, they do operate in a stackwise manner, but the device itself is a filter made with mese (well, extra mese). Therefore, it's a "Mese Filter".
