Add an end result cache fast-path

[PaintNinja]

Currently Mavenizer goes through each step, checking its cache before proceeding to the next step. While this is good for incremental builds, it's a lot of redundant checks for the common case of running Gradle tasks after project setup.

I'd like to request an end result fast-path added to Mavenizer - it'll check against the final result instead of going through all the steps, falling back to the per-step cache if the final result is a cache miss.

Yes, and also this solves the occasional issue of cache steps hitting but sometimes it may miss the final end result (it was a bug I think I fixed, but I forgot since it's been a while).

Ironically, this may also remove the need for log capturing. I'll play with the idea later.
