Add total number of reads to summary json/tsv

[kdm9]

This PR adds a count of the total number of reads to the machine readable outputs of load-into-counting.py (TSV/JSONs).

It takes the sum of the number of reads processed from the khmer.ReadParser object which is used for hashing across all read files.

I've also bumped the "mrinfo_version" tag in the json output to 0.2.0, FWIW.

Cheers,
K

Also apologies if jenkins or others complain about a commit to master, I accidentally changed to master between the above commits, and pushed the change. I've reverted it.

jenkins retest this please

Ah yes, one of these things:

• Is it mergeable?
• Did it pass the tests?
• If it introduces new functionality in scripts/ is it tested?
  Check for code coverage with make clean diff-cover
• Is it well formatted? Look at make pep8, make diff_pylint_report,
  make cppcheck, and make doc output. Use make format and manual
  fixing as needed.
• Did it change the command-line interface? Only additions are allowed
  without a major version increment. Changing file formats also requires a
  major version number increment.
• Is it documented in the ChangeLog?
  http://en.wikipedia.org/wiki/Changelog#Format
• Was a spellchecker run on the source code and documentation after
  changes were made?
• Is the Copyright year up to date?

Made mergable after change to master, ready for review @mr-c @ctb et al 😄

(P.S., I see you all pinging each other to say a PR is ready for review, is this what you'd like external contributors like myself to do too?)

@kdmurray91 LGTM! Yes, please continue to @ mention us when you are ready for review. The full list is at http://khmer.readthedocs.org/en/latest/dev/getting-started.html#claiming-an-issue-and-starting-to-develop item number 12 (this was formalized during the coding sprint at PyCon).
