test data that has multiple output classes

Ouch, I thought the output was mostly csv. I was wrong.
use --delimiter="%" for this new test data
write a failing test for multiple csv output

Apparently wmic can return multiple csv files.
rewrite output parser to handle multiple files

Just merge the files together. In the future it might be important to
check whether or not there are a different number of columns.

There's one failing test, but it's unrelated (sort of).
fix a failing test by mocking more things

The test was written poorly.
Merge branch 'handle-multiple-classes' into master
