Documentation references runsample-output-directory that does not exist

[necrolyte2]

There are two pages

• http://ngs-mapper.readthedocs.org/en/latest/pipeline.html#pipeline-output
• http://ngs-mapper.readthedocs.org/en/latest/analysis.html#output-from-runsample-explained

Both reference runsample-output-directory which does not exist.

It seems that it probably did exist but somehow was removed?
