Simple is beautiful. The progress dialog has been removed from client as it is generally not needed. Also there are a lot of code cleanups in client.
A lot of client logic has been moved to the libsiilihai. This makes it easy to write client applications with less code. It paves way for the mobile version which has been planned for long time.
Edit: This build is for Linux & Mac only. Windows build system broke down and will be fixed soon(tm).
