Ticket comment editor: make it less easy to ''Edit'' a comment when the intent was to ''Reply'' to the comment. This is especially important for the last comment, where there was little visual difference between the two modes.
- swap ''Edit'' and ''Reply'' so that ''Reply'' comes first
- give a visual hint that we're editing the comment by using a distinctive background for the textarea

Ticket notification e-mail template: add missing space separator.

i18n and notifications: don't translate the notification mail, as we currently have one notification mail which is sent to every interested party.

Anyway, picking the current language (the one of the user triggering the notification) is the wrong thing to do, so the best thing to do given the present status of the notification subsystem is to ''not'' translate the mail.

Closes #8903.

i18n: add missing `ngettext` in report_view.html and corresponding fr translation.

i18n: boring fr update, ignore

i18n: boring extraction, ignore

0.11.7dev: prepare version strings for an eventual [milestone:0.11.7] version.

TracMercurial: port r8963 fix to 0.12 and multirepos versions of the plugin.

TracMercurial: API compatibility with new `extsetup(ui)`. Closes #8891.

WikiFormatting: make it easier to write big tables by allowing a row to be written on multiple lines.

In order to prevent starting a new row, end the line with a '\' character, after the last `||`.
