Update PermissiblePEX.java
Post full error reports to gist

This way we don't go over the max URL length for github or our URL
shortener, and prevent those massive error reports that have become
common.
Redesign Superperms handling to fit more with the Bukkit Vision

It is now two components: RegexPerms to handle the regex-based
permissions lookup and SuperpermsListener to add the raw PEX permissions
to the superperms databases.

This allows several things:
- Disable PEX's injection of the permissible and still use the rest of
  PEX
- Allow PEX's regex-based permissions resolution to apply to all
  superperms providers being used.

Other bonuses:
- PermissiblePEX can now be used for thread-safe permissions lookups
  (The rest of PEX is NOT thread-safe)
- Parent-child handling has been rewritten. It should catch more cases.
  Please let us know if issues are encountered
- Minor cleanup of how we inject our replacement objects

Remove duplicate inheritance changed event call
Optimize permission registration with superperms

A few tactics:
1. Add permissions as children to a single permission which is then
added to the attachment, instead adding each permission directly. This
allows to only recalculate permissions (an expensize task) once,
rather than after adding each permission directly.
2. Depending on the type of event called, only update either the
permissions or the metadata, not both. This prevents collecting the
player's permissions or options unnecessarily.
Add visited groups tracker

This will prevent duplicate visits to inherited groups (and therfore
circular inheritance)
However, it prevents circular inheritance silently. I'd put a warning on
this when a duplicate group is encountered, but there are legitimate
cases where this can happen.

Unbreak group inheritance. Fixes #959
