Core/DBLayer:

- Rewrite Field class to be able to store both binary prepared statement data and data from adhoc query resultsets
- Buffer the data of prepared statements using ResultSet and Field classes and let go of mysql c api structures after PreparedResultSet constructor. Fixes a race condition and thus a possible crash/data corruption (issue pointed out to Derex, basic suggestion by raczman)
- Conform PreparedResultSet and ResultSet to the same design standards, and using Field class as data buffer class for both
* NOTE: This means the fetching methods are uniform again, using ¨Field* fields = result->Fetch();¨ and access to elements trough fields[x].
* NOTE: for access to the correct row in prepared statements, ¨Field* fields = result->Fetch();¨ must ALWAYS be called inside the do { }while(result->NextRow()) loop.
* NOTE: This means that Field::GetString() returns std::string object and Field::GetCString() returns const char* pointer.

Still experimental and all that jazz, not recommended for production servers until feedback is given.
