our example repositories snuck into the build dictionary.

Our internal_backend/repositories defines a couple of example repositories that our BUILD files can refer to.

Our BUILD Dictionary builder code looks at symbols defined in our BUILD files to figure out what do doc in http://pantsbuild.github.io/build_dictionary.html

So...

Give our old @manual.builddict() decorator a new optional arg, suppress.

Mark those example repositories with manual.builddict(suppress=True)

BUILD Dictionary builder checks for suppress==True and omits those

Adding a list of dirs to exclude from the '::' scan.  The CmdLineSpecParser

By default passes along the workdir as the one dir to exclude.
You can add more directories relative to the build root using 'spec_excludes' in pants.ini

Testing Done:
ci is green.

I also created a bogus BUILD file under .pants.d and ran build-support/bin/ci.sh locally and the tests still passed.

'goal builddict' : generate .rst and .html, not just .rst

before: running 'goal builddict' generates a couple of .rst files which we then give to Sphinx

after: running 'goal builddict' generates those .rst files but also a couple of .html files which we then give to sitegen.

If/when sitegen's in good shape, it'd be good to get rid of the .rst-generating part.

Most of this change is in src/python/pants/backend/core/tasks/builddictionary.py , plus new html templates.

There are also changes to some docstrings:

I replaced some sphinx-rst-isms with docutil-rst-isms (which also work with Sphinx).

And I replaced some lost docstrings which I removed with the "inherit docstrings" change because I "knew" they'd be inherited from a superclass.

And added some docstrings which have been missing for a while which I noticed because increased scrutiny grrrrr.

Testing Done:

Running sphinx on the generated .rst files now generates warnings :-(
I poked around 'em for a while, but eventually gave up.

Plumb new-style options into the Context.

Allows code to reference option values the new way.

Renamed the overloaded self.options in Command to self.old_options/self.new_options,
to avoid confusion. Previously these collided and the only reason it worked was that
self.options happened to be reset to the right one just before using it.

Change a single flag reference to use the new path, as proof that it works.

With this change we can not only register flags the new way but also reference the option
values the new way. Once everything is ported to use these, we can switch the parser to
the new one, and the transition will be complete.

Testing Done:
ci baking.
