Solved issues dependency versioning issues with Ignition

We were using a newer Guava jar than the one referenced by Ignition; Guava has since removed and/or refactored many things regarding MapMaker, which is the only thing Ignition uses from Guava. Had to rebuild Ignition-support.jar from sources to include the correct Guava library version.

I see two issues here:
1) We should get rid of Guava. It'd require a huge rewrite of Ignition - which brings us to:
2) Ignition development's been abandoned over a year ago. We should probably just get rid of it altogether.

That said, this is only a temporary workaround. See issue #2
