Fixes WORLDGUARD-4140.
Specifically, fixes not being able to break lilypads while in a boat,
even through the player would normally be able to.
Note that slowdown is client-side and getting stuck is due to Spigot
not updating the client when the break is cancelled, which are unrelated
to this issue (and not fixable by us).
Fixes WORLDGUARD-4124.
This will fix various issues with logging in to regions with these flags
set and then moving out of them, or when moving between two adjacent
regions with the flags set and then moving out.
Also fall back to caching to memory if SQLite can't be linked.
This is a common issue with (bad) server hosts who mount /tmp as noexec,
which causes sqlite's native binaries to fail to link.
* Fix material loading from config requiring minecraft: namespace.
* Fix disallowed-lightning blocks. Lightning entities are weird.
* Fix /wg reload overwriting config changes.
* General around thread usage/naming/shutdown. If anyone was actually
making their own managers/indices you deserve to break.
Note that due to deficiencies in the Bukkit API, the event will attempt
to be overprotective and cancel some events that may not actually result
in the player equipping an item. Maintainable PRs welcome. (i.e. would
rather not have to have a list of slot numbers for various inventories
and match them to items :upside_down:)
