Update the documentation.

Correct various bits and pieces so that the English is correct.

Replace instances of 'ipaddr' with 'vhost_name'.

 My earlier fork used ipaddr whereas the puppetlabs version uses
 vhost_name. Update the documentation to match the puppetlabs version.

Make some of the links in the README clickable
(#15008) enable AllowOverride setting in vhost

Permit passing an override parameter to apache::vhost; its value will be
plugged into the AllowOverride directive inside the docroot
configuration. The default value is ‘None’, so default behavior of the
module should not change.
Changed to match 'python_package' to 'mod_python package'

Matches the parameter name set in params.pp
Add no_proxy_uris param to apache::vhost::proxy

Add a mechanism to prevent certain URI's from being proxied.

This is particularly useful if you want to specify a proxy vhost pointed
at a webapp that installs itself under /SOME_URI in Apache's global
configuration. This is common on Debian and derivatives. Adding a vhost
for these is now as simple as:

   apache::vhost::proxy { 'manage.example.com':
     port          => 80,
     dest          => 'http://localhost/openstack-dashboard',
     no_proxy_uris => '/openstack-dashboard'
   }

Without this, you can easily get caught in an infinite, internal
redirect loop.
Added  to enable the user to specify the status of the vhost.
Addition of mod_auth_kerb mod, params & tests
Added an option to allow the user to specify the status of the vhost.
Corrected the error message.
Corrected the error message.
Changed the name of vhost status variable from vhost_ensure to ensure.
Merge branch 'master' of git://github.com/puppetlabs/puppetlabs-apache
Merge branch 'add-vhost-status' of https://github.com/martasd/puppetlabs-apache into add-vhost-status
Added dependency on stdlib.
Modified vhost type to use ensure_resource
Make the serveradmin vhost parameter optional

The original committer I think intended for this to be optional, but without a
default the serveradmin parameter is required.
