[super] (yet more) UX improvements to dataset edit, create and search

[rgrp]

TODO: great smaller tickets

See also: ​http://trac.ckan.org/ticket/1404 (Post-v1.5 UX improvements) -- probably want to integrate with this and subtickets.

Note: dataset (and resource) view UX improvements are #1450 and #1032

Dataset edit

• Fix (i.e. allow / show) name editing on dataset edit.
  • Fix the slugify so it does not overwrite if i change title after fixing name.
  • Make slugify encourage people to use shorter names. Either by cutting off (not so good) or showing a warning and saying something like 'hey you may want to cut this down. Hit edit to customize the dataset name now'
• Show edit summary form again, at least on edit pages (and prefill it for create to something sensible like: Creating dataset {title} {name})
• Fix drop down for resource types in resource add/edit to limit to fixed set of options (as per ​http://wiki.ckan.org/Domain_Model/Resource)
  • See also ​http://lists.okfn.org/pipermail/ckan-discuss/2011-December/001860.html
• Allow reordering of resources (or: and this is somewhat more complex but possibly simpler: allow editing of a resource_order field and we use that to sort resources (this is more like wordpress page_order -- these two options could become the same if we just hijack the existing position field on the join table and get rid of ordereredlist extension))
• Merge Groups and Tags into main Edit section (no point having them on their own and most people will miss this).
• Radically simplify set of licenses - #1359

Dataset Create

• ? Show Home Page field when creating dataset (+ show description (?) (-- but state that it should just be a few lines)
• ? Do some Guerilla UX to see whether we need to Redirect to Resources directly after dataset creation?

Dataset search

• Autocomplete / drop down on search (i.e. search while you type)
  • A 'Nice to have' but quite a bit of work (and should be a separate ticket)
