Fixed two little bugs.
Fixed a bug preventing mergetag from saving headers it read.
Fixed a bug where Input.event() would cause a segfault when no config was loaded. Now it fails silently, to avoid message spam on every single event.
As a result, input config filtering via headers tag "Configs" now works (not particularly useful though).
