#1 man_deblob.sh and man_rebrand.sh incomplete

man_deblob.sh should get rid of all references to non-free software, drivers, fw, etc.

man_rebrand.sh should replace OpenBSD or .Ox with LibertyBSD when appropriate. Appropriate:

• When a specific version of OBSD (that has a LBSD counterpart) is mentioned
  • I.E. ".Ox 5.9" becomes "LibertyBSD 5.9", while ".Ox 5.4" does not change.
• When OpenBSD is referenced in general.
  • I.E. "The OpenBSD operating system" becomes "The LibertyBSD operating system" Inappropriate:
• When OpenBSD developers are referenced
  • I.E. "The OpenBSD developers" does not change
• When someone is listed as an OBSD dev
• When an OBSD version without an LBSD counterpart is mentioned
• When the OBSD Foundation is mentioned

man_rebrand is completely done (AFAIK). (There might be a few accidental rebrands where OpenBSD makes more sense, I'll take another look later.)
I ended up implementing it completely differently from the bug report's description.
Instead of making ".Ox 5.9" "LibertyBSD 5.9", I decided to keep it as ".Ox 5.9". I realized this made a lot more sense-- after all, the man page didn't come from LibertyBSD x.x, it came from OpenBSD x.x. (Usually, version numbers are mentioned in the "this man page was first included in..." section.)

Will need to replace release(8) for sure.
