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 :) )

No one liked to see overexposed in preview :(

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.
