remove presets from /admin/build/imagecache title

clean up height/width settings for imagecache_scale_and_crop to compensate
for auto scaling on 0 in imageapi.

add path formatter
move hook_requirements to .install
add more requirements... check directories and memory_limit.

update for latest imageapi...

removed lingering dsm

Wrote my own imageAPI that does image ops without writing the files... The output is much prettier...
Still a little slow...

the crud api around actions is complete.

The presets list and add on the new admin UI is done. Delete is next followed by
the actions section...

oops forgot to add imagecache_actions.inc... I've got to backtrack and rewrite some code now :( I deleted my
local copy... I'm probably going to rewrite the UI first.
