Arrow render fixes (#141)

* Raise alpha values on arrows for better visibility

* Fix hover test for drawing arrows.

Width and Height of quest icon were not accounted for.

Bad smell: Used hard-coded width and height of quest bounding box

* Broke conditinal across lines for readability

Followed Google's Java Style Guide; unsure if that's apropos for this project.

Real coders, apparently, never soft-wrap... or so I've been told. ^^
