jacoco version bump for java 8 compat
refactor: org.whdl -> org.manifold
Modifications to intermediate representation

Some things here that we should probably discuss...

1. I'm confused why so many things are/were mutable. Do we actually need
mutable values for stuff like the attributes? I almost wrote some type
checking for those vs. the actual attributes defined in the type but
didnt since I feel like it would be better to set attributes on
construction and just not worry about them anymore. 

2. I made a change which gives nodes better ownership of their ports,
but I'm still not entirely satisfied with this. This partially ties in
with #1.

3. Made some changes to a few unit tests that were giving issues, using
the @Before junit annotation to get rid of some duplicate code.

4. We should add a task to refactor everything to use the Attribute
code.

5. Current serialization is actually broken since adding the parent node
introduced a cyclic dependency, causing a stack overflow :P That test is
on @Ignore for now until I write the actual serializer.

GAAAAH this merge was so dumb. I just took my version of each file
because the diff was being dumb and just marked entire chunks of code as
being different. I don't think anyone had conflicting changes with me
(let me know if there are)

Removed Definitions... again...

The diff was poorly displayed. This should get it back into the same
state. Let me know if there's any other changes that I need to apply.
