[MONDRIAN-1488][MONDRIAN-1501] - Issue with HighCardSqlTupleReader logic where .remove was being called on a list which doesn't support it in order to rearrange null members.  HCSTR does not need to bumpNullMembers, however, so removed the call.
MONDRIAN-1464 - steelwheels schema incorrectly typed year_id as a String.  This prevented Mondrian from being able to figure out that a non-existing member should be treated as the #null member.
MONDRIAN-1464 - disabling test when steelwheels is not available
Fix for MONDRIAN-1492. The MySQL dialect was removing all case sensitivity flags and ignoring them when generating SQL, thus forcing everything to be case sensitive.
Small woopsie for MONDRIAN-1492. A test in NonEmptyTest was also using regexp matches. Had to be updated.
Fix for MONDRIAN-1510. The Sybase dialect needed to override requiresAliasForFromQuery to make sure that an alias was appended to sub-queries.
Update ivy.xml

Remove release build-breaking transitives from this naughty circular dependency.
Add review comments to ImpalaDialect.
Augments the default size of CellBatchSize. According from the overwhelming feedback from services & customers, 5k was a ludicruously low default value. I'm cranking it up to 50k, which is a reasonable and safe value. Most users set it to 100k or so without problems related to memory consumption or concurrency issues.
Reverting OracleDialect back to 6e23ba0 to verify how Oracle sets precision and scale on certain columns with GROUPING SETS.  Expecting CI failures on the Oracle suites.
Switched OracleDialect back to treating scale=-127 / precision=0 as an int to handle the GROUPING SETS case.
[MONDRIAN-1496]  java.lang.ClassCastException: mondrian.rolap.RolapMemberBase cannot be cast to mondrian.rolap.RolapCalculatedMember. When looking up the $scenario property we were failing to verify the member is a scenario.
Fix for MONDRIAN-1499. If no alias are present, substitute the name of the table.
CM-371 - Removed the use of .tar.gz in favor of using .zip with file permissions stored in the zip file.
[ANALYZER-1618] Subtotal not displayed after being enabled.  This was a case where a Level (National) had the same name as a member in the level.  When referring to children of this member Analyzer uses the form Dimension.Level.member.member, which was not correctly resolved on the axis.
Checkfile correction.

[MONDRIAN-1560]  Some member references can be case sensitive, even when mondrian.olap.case.sensitive=false
