#318430 by dman and drewish: Show a 'preview' image when editing imagecache presets, for easy testing.

Small UI improvement, when there are no actions on a preset go ahead and expand the fieldset with the list so the next step is clear.

fix a type in imagecache_actions.inc.

d6 port.

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.

#201762 by jpetso, doxygen fixes
#201757 by jpetso, use basename in place of str_replace
#201640 by jpetso, hook_requirments array key fix clean_urls should be imagetoolkist

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.
