GPII-135: Upgrading Infusion

Upgraded Infusion to get the low contrast themes
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
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.

GPII-135: fixed a bug with toggling contrasts

There was an issue with toggling contrasts, where after hiding and showing the discovery tool the display of the selected contrast preset would be out-of-sync. This was solved by adjusting the listeners for the contrast presets.
