v1.2.0b

This release primarily features better support for large projects and groups.
Downloads of large groups are dramatically faster and now only require a
constant amount of memory no matter how large the group is. Also a progress bar
is now displayed when opening a large project.

A few more link types in CSS and <script> tags are now recognized.

Last but not least, phpBB forums are now recognized specially and can be
downloaded effectively without creating an explosion of URL combinations.
phpBB support is still experimental and likely requires additional tuning.

For more information see the release notes.
