allow doubled avatar resolution

Browse Source 
up to now, avatars were restricted to 20k, 256x256 pixel.
resulting in often poor avatar quality.
(the limitation comes from times
where unencrypted outlook inner headers were a thing;
this has changed meanwhile)

to increase quality while keeping a reasonable small size,
for "balanced quality",
we increase the allowed width to 512x512 and the allowed size to 60k.

for "worse quality", things stay unchanged at 128x128 pixel and 20k.
