again an experimental Smack to fix IBB transfers for Spark 2.6.3. This is an experimental build with patches based on the Smack 3.2. branch. The patch itself is published in SMACK-351
The Smack code is not using IQ Stanzas for IBB file transfer since the implementation is not correct. Smack 3.2.1 also breaks file transfers via IBB to Spark 2.5.8. This alpha should fix:
Copy into the lib folder of the Spark installation folder and report results.
P.S. Also fixes SASL against jabberd2 since http://issues.igniterealtime.org/browse/SMACK-324 is included.
