MDL-35653 - mod/wiki: Force format now lets users edit wiki pages.

Thanks to Tõnis Tartes for part of this solution.

When force format was selected in the options, trying to view the
wiki would redirect to the front page with a message saying that
you do not have permission to edit this page. Students had no way
of viewing any entries or creating the first page.

When in force format it skips a page , which would be considered
uncessary for students, but this means that the group id is not set
and this is what is causing most of the problems.

I also have included a check to see if the title is default and whether
the user has permission to view all groups. In these situations the
intermediate page is displayed.
MDL-36934 Only set the autosubmit class on selects when required

The url_select class can optionally show a button (much like the non-JS
fallback). In this case, the autosubmit nature of the form shouldn't be
enforced and it should only submit on the button.

changing the maximum mark or the behaviour.
