generate code from the new obiee 11g test instance and accommodate differences

* the new wsdl has jaxb:package info in it, so we'll go ahead and use oracle's suggested package names
  * this does make the change backwards incompatible, but not many things directly use the generated classes
* remove jaxb and jaws binding files; they aren't needed anymore
use v7 instead of v6

(no breaking changes)
use branch-specific version number
disable tests for now
Change the checking for order by index, it now comes back as a newline rather than a space
slightly better error message
fixed rowmap sorting

* obiee 11g does not align sql queries with xml queries as nicely as 10g - there are extra columns
* however, it's not too difficult to use the xml api instead of sql api (in fact, this is less hacky than the old approach)
small cleanup
handle no-result cases differently

Answers does not return a schema if there is no data to return.
remove some duplication
handle case when stored report has no <saw:columnOrder>
activate and fix a test
Pass in report parameters so data will come back filtered properly.
add assertion to testSortByAmountWithDesigParam

(this showed the problem fixed by Bill in previous commit)
handle case when sorting is used and parameters select no data

(Answers does not send back the Schema metadata if there is no data, even if outputFormat = SAW_ROWSET_SCHEMA.)
This assumes the report definition stored in Answers will always return data.  We think this is a reasonable assumption.
remove unnecessary groupId
set version to 2-SNAPSHOT

this is not backwards compatible with the version in master,
so bump version before the merge.
