Update dependency on rincl-wicket to 0.8.0-SNAPSHOT

The rincl-wicket project has a dependency on the version 0.7.2-SNAPSHOT of rincl, but rincl was updated from 0.7.2-SNAPSHOT directly to 0.8.0-SNAPSHOT, which means that the vesion used doesn't exist anymore, so we need to fix that to keep the build working.
