ed 2bf9055cae detect free RAM on startup for sane defaults 
* if free ram on startup is less than 2 GiB,
   use smaller chunks for parallel file hashing

* if --th-max-ram is lower than 0.25 (256 MiB),
   print a warning that thumbnails will not work

* make thumbnail cleaner immediately do a sweep on startup,
   forgetting any failed conversions so they can be retried
   in case the memory limit was increased since last run
