Title: Fix format of metadata when outputting in tab-delim mode

Previously, when using the -f option with predict_metagenomes.py the format of the metadata was not nicely formatted (contained python markup since it was a list being output as a string). This PR will format the metadata nicely no matter if it is a string, list, or list of lists.

Also, update the script level usage documentation.
