High level resource caching; resource cleanup (#264)

* Work on resource loading

* Use new material flag name. (#261)

Update ebiten ref while at it

* Hopefully fix CI (#262)

* Don't try to copy config.json on travis (#263)

I doesn't exist anymore

* Update D2Shared references

* Fix character selection rect
