PicoTorrent 0.6 (32-bit)

What's new in this version:

Features:
- We removed a thread! The BitTorrent session no longer has its own worker thread, but instead integrates with the application message loop
- The peers list now shows a lot of flags (as in connection property flags)
- A new menu item in the main menu has been added which allows one to check for updates when PicoTorrent is running
- The tracker list shows more tracker statistics - like time until next announce and also peer count
- Libtorrent has been updated to commitish ee94ac6ef7152d622347dc7f51fc3bb98e81fdf5 which was the master head at the time
- Language support! :flags: PicoTorrent is now multi-lingual, and translating it is really easy with the simple JSON file format
- The torrent context menu now has an item to bring up the details dialog

Bug Fixes:
- When adding a torrent with lots of files (more than 256) there was a bug that made a uint8_t overflow
- If the last file in a torrent was set to Do not download, the other files would be set to some unknown priority. Also, if all files in a torrent were set to Do not download, libtorrent would post alerts in the wrong order
