A Proper lookup table that uses HashTable's API
...
This is the first step of allowing heterogeneous cells in hash tables.
performance test results are
```
1. HashMap<UInt16, UInt8, TrivialHash, HashTableFixedGrower<16>>;
2. NewLookupMap<UInt16, UInt8>

Make it compilable on OS X
...
It's still hackish and dirty, but server and client compies.
Server starts, but throwes meaningless exception on any query.
Client seems to be working fine.
Linux compilation might (but shouldn't) be broken (not tested).
