Patch which provides a way to indicate that a collapsed thread has flagged children.

[kaz]

Roundcube 0.4 has a useful feature, configurable through the skin variables and CSS, which enables the user to tell that a collapsed thread has unread messages. The subject line of the thread can be altered with CSS (bolded, underlined, etc). Moreover, there is the possibility of using a dedicated "unreadChildrenIcon" which is shown next to a thread with unread children. Such an icon is provided (blue star with hollow middle) but not used in the default skin.

This patch provides parallel functionality for flagged messages, making it possible, through CSS effects and a custom icon, that a collapsed thread contains one or more messages that are flagged.

The patch is provided in Ticket #1486701. (Some of the CSS changes related to unread messages may have to be scrubbed from the patch).

In #1486904 I provided a possible icon for flagged children (a hollow version of the flagged icon, similarly to how the unread children icon is a hollow version of the unread icon).

(Those above Trac items are about messages marked read, not about flagged messages, so the patch does not belong there, and has slipped through the cracks because the items are closed.)
