Title: Implementation of SSCursor, and dump_packet() Fixes

- Implementation of Unbuffered Cursors (SSCursor), for working with very large result sets,
or for working over slow network connections. Reads rows on-demand instead of
all-at-once.
- Implementation of OKPacketWrapper, and EOFPacketWrapper classes, which wrap
around the MysqlPacket class (similar to FieldDescriptorPacket).
- Use try/except:pass in dump_packet() function, to avoid throwing exceptions.

Changes as per discussion:
- Renamed to SSCursor
- Compatible with MySQLdb's implementation
- Unit tests included in pymysql/tests/test_SSCursor.py
