Remove some redundant "www."s.
Filename cleanup

Avoid spaces and parens, adjust code, change the r-logo name.
Improvify comment text.
Tiny typo.
Some style fixes.
Fix a bug in base conversion.

This is a simple fix, and the bug is bad enough that it might be worth
it to include in the release.
Switch from "x" to "*".

As previously discussed with Ryan.
