Release 0.3 alpha

I'm pleased to announce the release of the third alpha of FastDup, which is already the fastest tool to find duplicated files. Version 0.3 introduces new features, significant bugfixes, and a change of license to the GPL version 3.

The focus of the next release, version 0.4, is to find and fix as many bugs as possible. Please report any issues you have via email to special@dereferenced.net, or on the bugtracker. Patches and suggestions are always appreciated as well.

Changes since version 0.2 include:
* Changed license to GPLv3 due to problems with the non-standard BSD license
* Added an interactive-mode progress indicator while waiting for comparisons
* Added the - c (conditions) option, to filter which files are included in scanning. Usage is - c [+-=]1[bkmg] to include only files greater than, less than, or equal to one byte, kilobyte, megabyte, or gigabyte respectively. For example, -c +1m only scans files over 1MB in size.
* Fixed a compiling error when using GCC 4.3.0
* Resolved all remaining memory leaks, which were fairly minor

Thanks to Stephan Hegel, Ben McIlwain, and everyone who reported issues with the 0.2 release.

FastDup is currently available for modern Linux (or compatible) platforms only. Support for BSD, Windows, and other platforms is planned for future releases.
