Fixed: removed settings.viewerX/YOffset

-Removed text.js plugin shell

-Removed references to settings.verticalX/YOffset and replaced with accurate, up-to-date value where previously used

-Condensed padding code during init functions; pageTools is placed at top regardless of orientation so horizontal padding should stay the same regardless.

-How did I set verticalPadding to be the max of 40 and horizontalPadding? Sometimes I baffle myself.

Fixes #218.
