Ignore intellij files
We've started publishing snapshot builds of MDS via PIH's bamboo, but I think that only keeping the most recent snapshot around is good enough (i.e. we don't need to maintain snapshots for every commit, just the latest for 1.1-SNAPSHOT).
Removed uniqueVersion=false, which is no longer supported in maven 3
