Addressed Issue #1922350 by slayne40, rjacobs: Juicebox views arguments are not properly collected from XML path

Addressed Issue #1922372 by slayne40: Juicebox library version detection does not work for older Jucebox versions (< v1.2)

Addressed Issue# 1885684: Add validation to Juicebox settings AND Issue# 1885670: Allow multiple Juicebox galleries to be displayed in one page, etc.

Decided to revert techniques that cache XML conf details. The way this was setup was not going to be friendly to views filters that are not tied directly to views arguments (multilingual variables, etc.)

Improved the way view style options (related to fields used in the gallery) are managed and implimented. Also added library version detection (libraries API).
