jQuery UI integration

[psuter <petsuter@…>]

Ship ​jQuery UI with Trac. (I assume this is the plan, but I couldn't find a specific ticket. It was discussed before in light of these use cases: Search suggestions #9643, Tooltips #9648, Datepicker #2288, Column reordering #7026 and in general on the ​mailing list.)

Some points that may need to be addressed:

• What to include? (jQuery UI comes as a bag of interactions, widgets & effects one can pick and choose to create a custom package.)
• What theme to use? (jQuery UI offers a collection of standard themes and a ​custom theme roller.)
• What Advanced Theme Settings to use?
  • CSS Scope:

    This field allows you to specify a CSS scope to limit your theme to a particular portion of a page. This is helpful when using multiple themes on a page. If you don't provide a CSS scope, your theme will apply to all UI elements on a page. In most situations, you won't need to specify a CSS scope. Please Note: If you provide a CSS scope, you will not get an example page included in your download.

  • Theme Folder Name:

    This field allows you to specify a name for the theme folder in your download. This is helpful if you plan to use multiple themes on a page. It defaults to "theme".

• Where to place the files?
• Should we call add_script / add_stylesheet in trac.we.chrome.Chrome.prepare_request as for jQuery?
