This is LOOT v0.9.2's API, modified to wrap the LOOT C++ API at
5982136f71cd026ecf80a7b6c7b9dd53e0dcb8d5 (the commit may be rebased
out of history, but it's the first iteration of the C++ API with
the Error class exposed).
Changes from the v0.9.2 API include:
* a different header name (c_api.h)
* a different DLL name (loot_c_api.dll)
* loot_cleanliness codes that replace the loot_needs_cleaning codes
* loot_get_tag_map() has been removed
* loot_get_plugin_tags() now returns tags as strings
