edje - reduce anothr 400k or so of memory usage (esp hello world)

so edje was allocating 32 pointers per collection. this is per
collection inside an edje file even if we just use one collection from
that edje file. it consumes 32 pointers. on 64bit thats 256 bytes...
just for pointers to mempools so we can "optimize" freeing and
allocation of parts. this was simply rediculous. i moved it to a
sub-struct allocated on demand (so now only for collections we
actually use) and this nuked 400k of "base memory usage youcant get
rid of).

note that our current default theme has something like 1100 or so
images, 1500 or so collections in it. as theme gorws, memory footprint
goes up if we dont allocation only on demand (when needed/used) and we
aren't careful about the size of our data structs and their content.
