Minor updates to TinyG Driver.
Merge branch 'develop' into feature/openbuilds-machine

* develop:
  Camera rotation is now supported in AbstractCamera and OpenCvCamera. Still not sure if this is how I want to do this or not, so leaving it open for now.
  Removed dead outlines.
  Whoops, put it on the wrong spot!
  Added basic .travid.yml, testing it.
  Pads are looking pretty good. Implemented roundness and rotation. Cleaned up lots of code. Totally broke everyone's packages. Sorry.
  Started to flesh out Eagle loader using JAXB
  Quick first pass at footprints. Probably need to get rid of OutlineReticle and FootprintReticle and just make a ShapeReticle. Still not quite sure about the model of Footprint / Pads.
