Remove WVE and BPS reference identifiers

Reasons why they should be gone:

WVE:
* wirelessve.org is down.
* Not a single module uses WVE as a reference

BPS:
* "BreakingPoint" no longer exists
* The URL takes you to a login page to ixia. And there is no point
  of referencing something people can't see.
* Not a single module uses BPS as a reference.
turn nil publics and privates into blanks

don't pass nil into the credential object, pass an empty string instead
this is the expected behaviour and avoids stack traces
