Improve the loading of serialized Bullet files, so that

after 'loadFileFromMemory' you can save the existing memory back to disk converted to native architecture endianness.
Fixed a bug that prevented big endian machines to load cloth data (due to wrong endian swap of pointer array)
Also improved the 'preswap' so that you can swap endianness on big endian machines (to little endian)
