misc

fixed the recent messed up colours in PSD thumbnail generation. I enthusiastically 'fixed' a problem with greyscale PSD thumbs at the last minute last week and accidentally swapped the RGB colour channels on coloured ones. I changed the badly named method that caused this mixup, and all existing PSD thumbs will be regenerated (issue #1448)
fixed up some borked button-enabling and status-displaying logic in the file history chart. the cancel process should work properly on repeat now
made two logical fixes to the archive count in the new file history chart when you have a specific search--archive times for files you deleted are now included properly, and files that are not eligible for archiving are discluded from the initial count. this should make the inbox and archive lines, which were often way too high during specific searches, a little better behaved. let me know what you see!
added a checkbox to options->thumbnails to turn off the new blurhash thumbnail fallback
'this has exif data, the other does not' statements are now calculated from cached knowledge--loading pairs in the duplicate filter should be faster now
some larger image files with clever metadata should import just a little faster now
if the process isn't explicitly frozen into an executable or a macOS App, it is now considered 'running from source'. various unusual 'running from source' modes (e.g. booting from various scripts that mess with argv) should now be recognised better

moved 'recent tags' code to a new client db module
moved ratings code to a new client db module
moved some db integrity checking code to the db maintenance module
moved the orphan table checking code to the db maintenance module
fixed the orphan table checking code, which was under-detecting orphan tables
moved some final references to sibling/parent tables from main db method to sibling and parent modules
moved most of the image metadata functions (exif, icc profile, human-readable, subsampling, quantization quality estimate) to a new HydrusImageMetadata file
moved the new blurhash methods to a new HydrusBlurhash file
moved various normalisation routines to a new HydrusImageNormalisation file
moved various channel scanning and adjusting code to a new HydrusImageColours file
moved the hydrus image files to the new 'hydrus.core.images' module
cleaned up some image loading code
deleted ancient and no-longer-used client db code regarding imageboard definitions, status texts, and more
removed the ancient OPENCV_OK fallback code, which was only used, superfluously, in a couple of final places. OpenCV is not optional to run hydrus, server or client
