Update CrossWords to 4.4.162
Change to build the latest release. The release is specifically for f-droid, where the build's been broken since I added an open-source library from a Maven repo that the f-droid build system doesn't allow. As a workaround this release removes the library so that users can get the fixes and features being added that don't depend on it.
Tested by building, installing, and running a small set of tests (mostly to ensure that network play still works without the library (which supports the MQTT protocol.))
