* std::unordered_map implementation in MSVC 10 has terribly slow destructor. Since bug is fixed only in VC11, I replaced it with boost::unordered_map.

* fixed crash with invalid .lod archive (some H3 installations have fake 1 byte .lod "archives"
* fixed crash when parsing invalid map file
* minor random optimizations (rv-refs, etc)
