Main Changes:
* Hacked together fancy new thing custom-op mode to make it possible to go through and selectively archive screenshots, while moving the old ones out into their own folders.
This makes it easier to archive a whole bunch of the less important ones, then just delete them from the phone 1-2 years later to free up space
(Unfortunately, web-browser ones cannot be distinguished from the filenames alone, and will need OCR processing integration to solve later - I have a tool I can integrate, but I'd like to switch that away from Windows OCR since I'm moving away from the platform soon-ish, and need these tools to keep working)
* Hacked together another custom-op mode that only does the moving-between-directories on phone too
* Then plugged a whole bunch of cases where timeouts could bring down the ship, by wrapping all the native calls with a wrapped-API that makes it retry several times before giving up
* Then bolted on mechanism to get these custom modes to run before a nominated main mode (i.e. so the "main / fixed" one won't double-capture these files)
