DataTables: Update to the development version of 1.10.4, which brings some fixes for data type detection.
Be more precise in the installation instructions in the readme files.
Remove all `@uses` PHPDoc tags, as they are no longer endorsed in the WP Core Documentation standards and show redundant information.
Add `@global` PHPDoc tags for important global variables.
Default CSS: Use `.tablepress` instead of `.dataTables_wrapper` in the selectors for the sorting arrows CSS, as only that is available in all table headers (e.g. also those from the FixedHeader Extension).
Update the readme files (add another bugfix, add list of updated languages).
Refresh tablepress.pot before the release.
Refresh German translation before the release.
