Servlet filter revert

GitHub Issue: Islandora/documentation#966

What does this Pull Request do?

Reverts the previous commit, and bumps the version number for when we slice a new one. We're going back to working with a Tomcat valve for the time being, so we can move forward with Fedora 5.

Additional Notes:

We'll need to slice a new version of syn. Use ./gradlew shadowJar to build the fat -all jar and attach that to the release in addition to the thin jar you'd get from ./gradlew build.
