this was an intermediate woriking state but got replaced by indivdual
dump skipping. forgot to remove it again

this allows for each dump being run within its own test case which then
can be skipped. This is needed to skip the django test on older PHP
versions.

this hopefully fixes the tests on travis

New Python Django application default to PBKDF2 with SHA256 as a
password mechanism. This adds support for that mechanism in our
password hasher class. This will be needed in the tests for the new
PDO auth plugin.

now all capabilities are covered

this makes sure manually assigned groups win on systems where only one
group is supported.

otherwise limit and offsets break in mysql

this configures a minimal wordpress setup
