css4j v1.0.3

This is the last release in the 1.x branch, with several backported fixes from the master (2.0) branch. An additional 1.0.x release would still be possible if a security bug was found, but users should not consider this branch as being
maintained.

Therefore, all 1.0.x users are encouraged to upgrade to 2.0 or later (please keep in mind that 2.x releases require Java 8).
