PN ASCII Editor beta 1.2

Another update.

Changelog:

- MDI Window layout: Multiple files opened in a single window
- If the name supplied by the file is wrong, the program generates a random one (not exactly random, but really weird).
- Render group info: why checking long tables if you can just click "info" to see what the selected render group does?
