Unify documentation

[JeroenDeDauw]

Right now docs are duplicated between the readme and the MW.org page, with the readme being incomplete and MW.org being out of date

I just updated the extensions page on mw.o, meaning that I removed all the stuff there except for the "Getting started" section which still needs to be moved to the README here. The rest seem to already be in a file within this repo.

This is not just about unifying documentation but also about initially creating documentation. However, I cannot be of further help here. I am just getting the summary field when trying to use the {{#signupfields:}} parser function within a form. I will probably ask on the mailing list after the release and go from there.

@toniher Can you help out here with a simple form that you used to check the {{#signupfields:}} functionality?

[toniher]

Sure, below a simple example:

This is the "User" form.
To create a page with this form, enter the page name below;
if a page with that name already exists, you will be sent to a form to edit that page.
{{#forminput:form=User}}


{{#signupfields:}}
{{{for template|Institution}}}
{| class="formtable"
! Institution: 
| {{{field|Institution|rows=3|mandatory}}}
|}
{{{end template}}}
{{{standard input|save}}}{{{standard input|cancel}}}

That's how you do it? I would probably never have guessed since this seem to be too simple. Will give it a shot later today.

OK, here is what I got (after 164576f):

$egSemanticSignupSettings['formName'] = 'UserSignupForm';
$egSemanticSignupSettings['botName'] = '...'; //Existing user with "createaccount" rights

Form:UserSignupForm

<includeonly>{{#signupfields:}}{{{for template|UserSignup}}}
{| class="formtable"
! Institution: 
| {{{field|Institution|rows=3|mandatory}}}
|}
{{{end template}}}

{{{standard input|save|label=Create account}}}{{{standard input|cancel}}}</includeonly>

Template:UserSignup

<includeonly>[[Institution::{{{Institution|}}}]]</includeonly>

then go to "Create account" and ...

As I realise now I had apart from incorrectly using the signupfields parser function another issue. There was a typo in the form's and template's name causing the failure on my side.

Done this commit ae00c94 to fluff things up. The rest would be tweaks I guess. Thanks to @mwjames and @toniher
