Subject: [PATCH] Started to implement libespm usage. Implementation is fairly
 hacky, with global common options handling and compiling it with LOOT instead
 of as a separate library. As a consequence of performance being much better
 than anticipated, the whole caching and sharing of plugin data idea has been
 scrapped, since it's no longer worth the effort of implementing. Also some
 YAML emitter fixes, general cleanup.
