Implement new classes:
* stdext::any => ligher replacement for boost::any
* stdext::packed_any => like any but optimized to use less memory
* stdext::shared_object => ligher replacement for std::shared_ptr
* stdext::shared_object_ptr => replacement for boost::intrusive_ptr
* stdext::fast_storage => for storing dynamic data
* stdext::packed_storage => same but with less memory
* stdext::packed_vector => std::vector with less memory
Compiling should be a little faster now because global boost including
is not needed anymore
* Can now filter market items by vocation, level, slot type, and depot items.
* Added new bitwise lib for handling flag operations.
* Can now get/set local player vocation/premium (TODO: spell list).
