AirDC++ 4.10

What's new in this version:

Improved transfers speeds:
- Version 4.10 allows the operating system to optimize socket buffer sizes, which multiplies per-connect speeds in many cases. Especially transfer speeds between users that have long physical distance between them will be increased
- Note that you will generally not see any speed improvements with people using previous versions of AirDC++

More reliable extensions:
- Extensions are now less likely exit due to a timeout when the system is under heavy load. If you still see timeouts, you may increase the socket ping timeout from the Web UI (Settings -> System -> Advanced server settings)

Changed:
- Let the operating system set the optimal socket write/read buffer sizes by default (can multiply per-connection transfer speeds with faster connections
- Improve hashing speed by increasing the read buffer from 256 kilobytes to 1024 kilobytes
- Increase the default file write buffer from 64 kilobytes to 256 kilobytes

Fixed:
- Fix inconsistencies with filelist transfer logging
