* Use target_include_directories to specify include paths
* Specify project root (parent of rtgui and rtengine) as include path
* Replace relative includes with normal includes
* Use mtime as fallback timestamp for files without EXIF data
As suggested in #6449, with date-based sorting it can be useful to have
at least *some* sort of time-relevant information for EXIF-less files,
to prevent them from falling back to getting sorted alphabetically all
the time.
This commit simply defaults the file timestamp to the file's mtime as
returned by g_stat. For annoying reasons, it doesn't suffice to merely
forward the timestamp to the FileData structs - we also need to keep
track of it inside FilesData to cover the case of a file with 0 frames
in it.
* Add DateTime to Thumbnail
Putting it here facilitate easier sorting without having to re-construct
the DateTime on every comparison.
To simplify things moving forwards, use the Glib::DateTime struct right
away. This struct also contains timezone information, but we don't
currently care about timezone - so just use the local timezone as the
best approximation. (Nothing currently depends on getting the timezone
right, anyway)
In addition to the above, this commit also changes the logic to allow
generating datetime strings even for files with missing EXIF (which
makes sense as a result of the previous commit allowing the use of mtime
instead).
* Implement file sorting in thumbnail view
For simplicity, I decided to only implement the attributes that I could
verily easily reach from the existing metadata exported by Thumbnail.
Ideally, I would also like to be able to sort by "last modified" but I'm
not sure of the best way to reach this from this place in the code.
It's worth pointing out that, with the current implementation, the list
will not dynamically re-sort itself until you re-select the sorting
method - even if you make changes to the files that would otherwise
affect the sorting (e.g. changing the rank while sorting by rank). One
might even call this a feature, not a bug, since it prevents thumbnails
from moving around while you're trying to re-label them. You can always
re-select "sort by ..." from the context menu to force a re-sort.

When opening an image, selecting the next/previous image or syncing the
Filmstrip, the newly selected thumbnail is centered, unless it lies
within the visible area more than 1 thumbnails-width away from either
edge, in which case centering does not occur.
The behaviour has changed slightly, so that clicking the menu item now resets
to the default processing profile specified in the preferences. If this
involves calling the custom profile builder, the behaviour is the same as
before. But this is a bit more general, in that it might also simply reapply
the static default profile, or regenerate the dynamic one (depending on the
user's settings)
