Make using SET or querying system catalogues harder

An hack to "prevent" querying system tables already existed but
was pretty weak. This commits makes that a bit stronger. The
filter for SET is new.
Another bit of improvement for the system-table query prevention

This work is more important for the testcases than the actual code
Rework system catalogue prevention access check to use CDB_QueryTables

This change reduces the chances of false positive
(forbidding legit queries). Doesn't solve the problem of false
negative (allowing illegit queries).
Allow sql queries to end with a semicolon. Closes #90
Fix test using wrong hostname (thus connecting to wrong db)
Fix exit code from test runner

Before this commit it would return success or failure only based
on whether cleanup was successful or bogus
Really fix the tests for unauthorized attempts to write db

It was not about specifying the db trough headers but rather
about referencing the _wrong_ database via params. Also fixes
the expected result (which was indeed wrong).
Report testsuite tweaks
Use a single server in the test for concurrent KML exports

A similar thing should be done for KML and Shapefile, but the focus
here is making jenkins happy for now
Raise mocha timeout to 5 seconds

.. still trying to please the jenkins setup
testsuite: insert all table values in a single statement
