GPII-134, GPII-124: Contrast theme for Discovery Tool more or less properly implemented. The text labels need to be placed in their own containers and top-aligned to the check icon. Fixed the text label colour to be more visible in default theme.

GPII-134: Put icon text labels into their own container and aligned them closer to the icon itself.
GPII-135: Upgrading Infusion

Upgraded Infusion to get the low contrast themes
FLUID-4947: removed a string length constraint.
GPII-135: Moved lib to shared directory

Moved the lib folder into a directory called "shared". The "shared" directory should hold anything that is shared between the preference tools (Discovery Tool, PMT, PCP). Current references into the lib directory have been updated with the new path.
GPII-135: Low contrast preset added.

Added the low contrast preset. However there needs to still be functionality to toggle between low/high contrast when setting one or the other. Meaning it should not be possible for both settings to be in the on state at the same time.
GPII-135: removed console log
FLUID-4947: added more improvements to announcements.
GPII-142: Header, breadcrumbs, prev/next, menu, etc. css tweaked

GPII-134: Merged changes from Master. Fixed positioning of checkbox in high contrast to be similar to the default view. Panel Bar now appears white on black.
GPII-142: Small chrome fix
GPII-135: created a new base grade for the panels.

Created a base grade for the panels that houses the common configuration. It also provides events to notify when the panel is enabled/disabled. this will be used for toggling off high/low contrasts.
GPII-135: toggling between contrasts

If one contrast is enabled and the other is activated, the original will be disabled.
