is pretty much almost perfectly working. i have fixed up some e_thumb stuff
and allowed e_thumb to be more responsive and skip items that are known to be
"generated" and bring them ahead in the list of things to thumb - so kind of
a priority skiplist - process what it KNOWS will be already done first
quickly and leave the slower stuff until later. efm is fairly well refined
now - as above. the test selector works nicely. also added an almost-sha1
generator - use sha1 sums of the path for thumbs - less likelihood of
collisions. the prolbme is given the small size of the input data... it's
hard to do well - but anyway :)
