clean up POMs

after toying around with Clojure's unit testing capabilities,
finally figured it out and cleaned up unneeded constructs
from project POMs (such as shell scripting to parse LISP forms,
which i can now do directly from Clojure). also upgraded JUnit
to latest version (although i'm not using it just yet),
and removed profile activations (which i'm also not using yet).

TODO: build out Maven modules to support building sub-projects
(spec, impl, inst) from a single parent POM.
add test resources

added a few test resources to help flesh-out a rudimentary
form-processing, e.g. reading EAI specifications in LISP format
from a file. this is still very raw and experimental,
but i wanted to capture some of the testing and form-reading
functionality i'd finally hammered out.

TODO: mock up LISP specs of additional EAI patterns.
