Fix long standing glitch in the display of labels in the grouped progress bar box in the Milestone view. In Firefox, the longest label used to be squashed to the progress bar itself.

This was probably due to the addition of white space in the Genshi template, and because of the `white-space: nowrap` CSS rule which applies here (btw, as it also applies to the <td>, there was no need to hard-code it again there in the template).

Resource-based permission checking added to the workflow code (plugins).

Minor fix to Image macro that did not accept `'px'` ending on width argument as documentation indicated. Now it supports both.

Make date input parsing more robust, as it turns out that converting back from timestamp later may lead to error if the date is outside a valid range (depending on platform) - usually larger than sometime in 2038.

Fixes #5322.

Fixing the order of some admin enums when modified through web-admin or trac-admin. Deleting a value left holes in the order, and made some strange ranges over time. Passes tests, and added some more to test the reordering.

As far as I can see, it is the name of the option (like 'defect') that is stored everywhere, with the order value is only used for display. Hope this assumption holds :-)

Closes #2876.

TracPlugins @45 integrated - some text on troubleshooting for plugin loading.
