AirDC++ 3.40

What's new in this version:

Added:
- AirDC++ Web API v1 (http://apidocs.airdcpp.net) and extension preview
- Save and load open tabs between sessions
- Back up successfully loaded XML setting files and recover corrupted ones automatically

Changed:
- Don't queue new background searches if the search queue is too long
- Simplified share monitoring that relies on directory refreshes instead of handling individual files
- Failed bundles won't be rescanned on filelist refresh (rescan must be initiated manually instead)
- Show recent private chat and file lists in Recents window
- Updated validation and reporting for ignored shared items

Fixed:
- Fix issues with displaying of various less common character symbols (or sharing files containing them)
- Fix sharing of directories from the initial configuration wizard

Removed:
- Option to hash finished bundle files
- Option to add finished finished bundles in share instantly (always shared instantly from now on when inside a shared directory)
