Patch (mostly stolen from the forbidden-api setup) switching to using <ivy:cachepath> to download the JFlex 1.5.0 jar from Maven Central and use it from there, rather than the previously required locally-built-from-source JFlex jar.

FYI, after the switch, I had to increase the JVM max mem in my ANT_OPTS environment variable from -Xmx1g to -Xmx1040m in order to get JFlex to generate UAX29URLEmailTokenizerImpl.java without OOMing.

Committing shortly.

LUCENE-5411: Upgrade to released JFlex 1.5.0; stop requiring a locally built JFlex snapshot jar.

Committed to trunk and branch_4x.

Unfortunately, the version reported by JFlex 1.5.0 is still "1.5.0-SNAPSHOT". Not sure whether 1.5.0 can be redeployed on Maven Central - if not, there will have to be a 1.5.1 release.

I'll keep this issue open until the SNAPSHOT problem is resolved.
