Docs changes

I pulled latest develop, then checked-out enhancement/14949.

Warnings

File dev/vagrant.rst, line 6: change:

`Vagrant <http://www.vagrantup.com/>`_

to:

`Vagrant <http://www.vagrantup.com/>`__

(an anonymous link, this way we don't have a repetition warning.)

File getting_started/installing.rst, last paragraph: change it to:

Congratulations!  |gwm| is now installed and initialized.  Next, you'll want
to look into :ref:`configuring` and :ref:`deployment`, if you are going
to be setting up a production instance.  Otherwise, if you just want to
play around with |gwm|, or are :ref:`developing <development>` |gwm|, take
a look at :ref:`development-server`.

Errors

Run:

sphinx-build -W -b linkcheck source ./build/html

You'll see a couple non working links (and a lot more working) - it might be wise to fix them.

Content

Style

At static-files label (whole paragraph): use double apostrophes instead of single (line 40).

Others

At deployment/apache.rst (last line): wrong settings file name. Should default to the one installed via setup.py, ie. config.py, right?

At deployment/nginx_site.conf:2: I heard that using Unix sockets is not only faster but also safer than URIs. It might be worth mentioning.

At deployment/uwsgi.ini:6: should it be ganeti_webmgr.ganeti_web.wsgi?
