- Fix url to forum.

- Fix Bit8u instead of char weirdness for imageDisk (dreamer_)
- Give device_t a virtual empty destructor so some warning program
  doesn't go crazy.
- Give the code that moves the Z drive its own function for readability.
- Give sizes arrays default values again for warning program.
- Rewrite IMGMOUNT in order to exit early for clarity and attempt
  to group things together.
