ZBar for Windows

Original zbar project http://zbar.sourceforge.net exhibits several problems on Windows platform. We would like to solve it in the original project, but it's temporarily not possible. The zbar administrator probably has other occupations that are more important than tuning zbar to run robustly on Windows. We employ DirectShow technology to access video device.

First release is not yet done, but we are close to it. A test build and source code is available for download. Testers and bug submitters welcome.
