Apply hint/help classes more widely

[Ryan J Ollos <ryan.j.ollos@…>]

I like the styling of the hint and help classes, and have noticed some places that I think it could be appropriately applied.

Example of help class:

[Ryan J Ollos <ryan.j.ollos@…>]

Here is an example of the kind of changes I had in mind:

• ​bef1f02e: Applied the hint class to text on the Report Edit page.
• ​7b72499e: Separated the label text and hint text, as I think this will allow theme authors to locate the hint independent from the placement of the label, without breaking translations.

Here is the result - the two lines to the right of the labels have a new styling:

Here is a screen capture of the current state of things, for comparison:

[Ryan J Ollos <ryan.j.ollos@…>]

• ​61a40d63: Default padding for span.hint is 0, and padding of 1em for span.hint used on the Admin forms is set in admin.css..
• ​5ae38851: Moved p.help class from admin.css to trac.css, so that it can be used more widely within Trac.

I'll wait for feedback on the changes before coming up with a patch to implement these changes throughout Trac, but on first review, here is where changes would need to be made:

• (you may use WikiFormatting here): on the following pages:
  • Milestone Edit
  • Ticket
  • Admin Ticket System and Admin Manage Repositories
• Milestone Edit: Format: MM/DD/YYYY hh:mm:ss a should be wrapped in a span with class hint (like the Admin Milestone Edit page), rather than being wrapped in em, and the CSS rule for #edit em can be removed.
