Revert "temperature: kelvin is high, introduce kludge factor"

This reverts commit 0ef76b617f7552bdca5ea3d7291d1fe7f3d6ffc5.

it's kind of needed for the 1.1.x series because reload_defaults() is called before module->gui_data is inited, which
results in an estimated daylight whitebalance of (1,1,1) in that branch. master has fixed that some time ago,
so the values make sense without kludging (yay :) )

This fixes #9495.
Use a locally cached image if the original is not found.

This only put in place the circuitry to look for an image into the
local cache (default: ~/.cache/darktable) if not available on the
original location.

This simple command dt_image_full_path() has been enhanced to look
into the cache.
Add a way to set/reset an image to/from the cache.
Write the local copy status into the database.
Display the local status into the metadata module.
Add a white circle on the image box in the ligttable area for local copies.

This is a simple marker to see what are the images having local copy
or not.
Allow creation of xmp sidecar for local copies.

So, remove sidecar when the local copy is reset.

This is for safety purpose in case the database got corrupted.
New routine to check whether a file is safe to be removed.

This is used for file having local copy and in this case the
original file must be accessible.
Refuse to remove a picture when a modified local copy exists.

This check is done when the original picture is not available otherwise
we could loose editing done on the local copy.

OSX packaging: include curl-ca-bundle.crt into package
In full view on the lighttable, wrap around.

That is when pressing right arrow on the last image in a row we move
to the next image on the following row. Same thing for left arrow on
the first image of a row.

This makes reviewing all images more friendly.
