Adding <p> in some places.

Starting to move guest OS installation instructions into individual machine pages, rather than having all of them randomly in the general guest OS page.

Removing comment about IDE, since it was not correct.

Adding a simple and stupid man to html converter.

Renaming oldtestmips back to testmips.
