3.0 beta

[Stefan]

Dear testers,

There are some new features in the 3.0 version but most of the work has been done in refactoring the code and improving robustness. The UI has also gotten some needed polish here and there. Hope to add some requested features in later 3.x releases. Your comments are welcome.

Changelog:

• Preview of local audio, video, image and text files by long-pressing the icon.
• Support for SOCKS4, SOCKS5 and HTTP CONNECT proxies for FTP and SFTP.
• Added picker for folders.
• Compare action added. The action selects items that are missing or have a different size or modification time in the other folder.
• Show real-time transfer speed (option in advanced settings to enable average speed).
• Added a compatibility mode option to FTP sites to improve compatibility with some servers.
• Requires Android 4.1 Jelly Bean or greater.
