UX polishing and bugfixes

[zephod]

From Ira: PDF of bugs and suggestions is attached.

This ticket is included in release v1.5. Post-v1.5 UX improvements are collected in #1404.

DONE ?

• [dataset/edit]: Deletions are confirmed with a dialog box
• [dataset/edit]: Long URLs break the edit resources tab. Show name (& 'no name') with a pencil icon.
• [dataset/edit]: Rearrange the delete resources mechanism;
  • Use a little minus icon on the far left, followed by a pencil icon for editing.
  • The 'delete resource' button can become 'hide'
  • Deletions are confirmed with a dialog box
• [dataset/edit]: Rearrange the 'you have unsaved changes' warning;
  • Delete the little green plus sign on the right;
  • Try a flash banner instead (more general purpose & beautiful)
• [dataset/edit]: Try a pencil icon (+'hide' button) rather than the +/- buttons which look a bit like you're adding a dataset.
• [dataset/view]: Subscribe button (& subscribe to history) doesn't work as expected. Modal dialog carrying instructions?
• [dataset/view]: Drop the 'add to a group>>' and 'add tag>>'. Needs inline tag-adder.
• [markdown editor]: Tab colours confuse the user. Inactive button appears to be greyed out.
• [dataset/edit]: The upload file UI mutates and breaks across lines; make it a little more rigid. Verify at different zoom levels.
• [groups/add]: Hide unimportant fields
• [navigation] Add 3D bevel (@see github) to current tab highlight.
• [dataset/create and groups/create]: Slug generator can be tidied. Default: Not editable. @see ​http://groupspaces.com/a/group/
• [groups/view]: Show description and owner. To match dataset section.
• [groups/authz]: Tidy to match admin/authz (pretty buttons & spacing). Add navigation bar.
• [groups]: Entire section to use pretty buttons please.
• [about]: Get the about page working on test.ckan.org. (Works locally and on live).

WONTFIX ?

• [dataset/edit]: Make 'tags' a top level form section; it is too important to go below the fold. (wontfix)
• [groups]: Clicking a column heading should sort by that column. Default should be 'size', not 'name'. (ticket #1403)
• ([groups]: (Investigate) Is it easy to implement a little search-groups feature?) (ticket #1403)
• [*/authz]: Add tooltips to explain column headers. (Not required if mechanism is about to be refactored...) (wontfix: we need to rethink this mechanism; authorization refactor is coming)
• [general]: 'Authorization' refactor to 'Permissions' on nav-bars. (wontfix, further discussion. authorization might be less techy...)
• [search]: (Investigate) Can we quickly & easily reintegrate the faceted search-by-license but present it in the sidebar like the other facets? (wontfix: high cost and maintenance overhead; need compelling user story)
