Allow question types to be displayed in order that is better than random or alphabetical. Since we don't know all the qtypes there may be:
1. Store the order in the DB (config plugins).
2. Set up a good default order for the standard types. (Unknown types go at the end by default.)
3. Allow admins to edit the order on the qtype admin screen.
That allows us to have a few sentences explanation of each question type, and is also easier to fit into a tight layout.
This commit should also fix MDL-18214 Layout screwed in Safari with long category names.
Also MDL-17585 Improve layout of manual grading forms to make them look more like formslib forms. The standard trick of stealing the HTML and class names that formslib works, so the standard style rules apply to your form.
* Rewrite all the forms to use formslib and improve usability.
* Put the place where admins need to go to process approvals in the admin menu.
* Show the request course/pending requests button on the page for the category that requested courses get added to.
Bugs: MDL-17479, MDL-16426, MDL-16063, MDL-16013, MDL-15658, MDL-15556, MDL-15161, MDL-14925, MDL-13742, MDL-11557.
* Simplify category editing permissions to just moodle/category:manage and moodle/category:seehiddencategories.
* Enforce those correctly. (Note MDL 17502 is still outstanding.)
* Don't screw up category sort order when you just edit name or description.
* Niceties like where redirects go when you cancel or submit forms.
* Make sure a global course creator can see the site admin block.
* Don't allow a category to be made the child of one of its children!
* General code cleanup to bring key files more in line with best pracitice.
Apologies for the fact it is one big patch, rather than a series of smaller patches. However, categoryedit.php, category.php and index.php where in pretty bad shape and needed significant cleaning up. categoryedit.php, in particular, was almost completely rewritten.
Merged from MOODLE_19_STABLE.
made the link in an empty random question more readable, added a link to show category contents after the list of sample questions of a random question
Well, that was a stunningly creating IE layout bug, and I have no idea why this work-around works. (The margin 0 and vertical-align are the essentail bits, the other two rules just make it look nicer.)
Also tweaked the layout in Firefox to position the icons a bit more nicely.
