The hints given via DBus are not constants. Therefore the color fields
have to get freed during notification cleanup. As it's not possible to
disinguish, which field is constant, we have to duplicate the settings
on assignment.
While the notification spec allows tags like <a href="...">...</a> and
<img src="..." alt="...">, pango cannot parse these tags and therefore
these tags should be removed before passed to pango.
Also the method notification_extract_markup_urls is not needed anymore,
as markup_strip_a can return URLs optionally.
This implies, that URL replacement is now indicated via show_indicators
for URLs and the dmenu string is in the format of
'[text between a tags] URL\n'. This is similarly handled for images,
too.
As GApplications expose their icon via image-path hint and not via the
actual app_icon field, GApplication icons haven't been displayed before.
According to the notification spec, image-path hint should also override
the app_icon as follows:
1. image-data hint
2. image-path hint
3. app_icon parameter
Notification spec prohibits to reuse notification IDs (unless uint32 is
exhausted). Therefore returning the same ID twice must not happen.
Sending a signal, that the old notification timed out makes most sense.
It wasn't closed by the user, nor by a CloseNotification call either.
When we stack notifications, no interaction happened (the equivalent
of timing out).
Due to the way Xlib handles errors XRRGetMonitors will cause dunst to exit if
the server doesn't support version 1.5 of RandR. The check for null is
effectively dead code but in theory the number of monitors can be < 1 so treat
this as an error. Change the code to fetch the RandR version and fallback if
the version is less than 1.5 when getting monitors.

There is no need save if the icon field should have precedence, as
setting raw_icon to NULL emphasizes the same.
Also freeing raw_icon saves unneccessary memory.
Move all id-changing functions out of notification_init and handle this
in queues.c
Also use stack_duplicates in combination with replacement of
notifications correctly. Fixes#404 (issue not found)
