the Waba tools add an icon (along with other graphics and Java .class files)
but since they use a standard application .pkg template, they either rewrite
some information in known locations, or properly add things to end of .pkg
and update the appropriate objects and references.
(trying to patch an icon in random packages would be messy/tedious)
another approach is to write a tiny application or extension (basically just
an InstallScript) that just patches how the application appears in Extras
rather than modify the app's pkg directly, using:
call kAddExtraIconFunc with (iconType,paramFrame,pkgName, store);
