* Add Timings for third-party session handlers.
These often cause WorldGuard to get blamed by timings.
* Add config option to turn off extra timings.
* Move relocation to the right build file.
* Move config to a map for potential future expansion.
* Calculate timing immediately per-factory.
Instead of on each handler creation.
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.
