Committed changes for version 2.5.0:
* Fixed bug on 'Manage Release' page where after 2.4.0 the same report was shown for all releases.
* Removed ob_end_flush() before streaming download as this has caused issues for users. If with this measure new issues would pop-up this needs to be made configurable.
* Included optimizations from Max Brokman (initialization of $num_download_files, $id and $bar, inclusion of $wpdb->prepare() for security reasons).
* Added ID of release to 'Manage Codes' page so that it is easier to determine which ID a release has.
* Added shortcode example to 'Manage Codes' page in order to simplify the insertion of shortcodes into pages.
* Fixed behavior with multiple shortcodes appearing on the same page so that only results and links are shown which are related to the release for which the code was entered.
* Added experimental functionality to define an anchor with a shortcode (e.g. [download-code id="3" anchor="myanchor"]) in order to allow people to automatically scroll to the download link after the code was entered.
