Add utility functions from QIIME

I initially work these functions for QIIME, now ported to be used here
in Emperor.
Add function to get Emperor's autograph

This function will collect data within a process that was started by
make_emperor.py.
Fix HTML comment formatting

Additionally the signature has now been extended to be 10 lines so users
can easily do head emperor/index.html to get the information they
require.
Visualizations now include data about Emperor

Each visualization is now tagged with 10 lines where information about
the creation of the file is included. This information will point people
to the version of the libraries that were used to create the files as
well as the date an which exact command was executed.
