Remove whitelist/blacklist references

[johnjamesjacoby]

The moderation API contains several references to the blacklist_keys WordPress option, going as far as naming functions after it. While this is not an uncommon practice, it is unintentionally maintaining an unhealthy, unwelcome, and historically hostile status quo.

To make bbPress as welcoming and inclusive as possible to all audiences, let's deprecate uses of "blacklist" and "whitelist".

Patch & commit incoming.

In 6855:

Moderation: remove references to blacklist/whitelist verbiage.

This change combines 2 functions into 1, merging _blacklist() checks into _moderation() checks. A new $strict parameter is added, when set to true will continue to check against the WordPress blacklist_keys option name.

• Tests updated
• bbp_check_for_blacklist() deprecated
• Error response keys renamed (non breaking - nothing relies on them)
• Some docs updates

Fixes #3215. For 2.6.

In 6857:

Moderation: allow custom keys to be passed in via the $strict parameter.

See #3215.

In 6858:

Moderation: add author-specific keymaster & moderation checks.

This fixes a regression where Moderators were allowed to skip strict moderation rules. Moderators are held to the same standard that regular users in the forums are.

See #3215.
