BSA enhancements.
* Implement hash based lookup for TES3 BSA files. * Added TES4/TES5 BSA support. * Implemented a hack (non-portable code) in an attempt to reduce startup time under Windows because Boost::filesystem seems to take forever on GetFileAttributeW. This implementation uses FindFirstFile/FindNextFile/FindClose instead.pull/1955/head
