GPII-153, GPII-187: fixed textfieldStepper guard

Fixed the textfieldStepper guard to handle parse string values inputed from the textfield. Also fixed up the unit tests, all are passing now.
Marked the "Magnifier Follows" files as deprecated since this adjuster
has changed for the PM tools in pilots 2.
GPII-364: Renamed contrast references to highContrast
Now contrastTheme adjuster is going to start be implemented.
GPII-364: Created the addContrast adjuster as a composite panel.
This will be the container for all adjusters of "add contrast" group.
Trying with highContrast adjuster as member of the composite panel but
with no success.
GPII-364: Cannot make the highContrast adjuster work as composite.
Temporarily made highContrast checkbox visible for testing purposes.
The contrast label is not in the composite base.

GPII-153, GPII-187: Added model relay into the new textfieldSlider component and use it in the speak text demo.
GPII-153, GPII-187: Removed modelRelay out of textfieldStepper into where it's actually used.
GPII-153, GPII-187: Replaced plusMinus component used in pmt textSize adjuster for incrementing or decrementing font size with textfieldStepper component.
GPII-153, GPII-187: Made the tool to not break.
Left only the cursorSize adjuster, because having both this and the
textSize adjuster seems to break it.
Fixed a typo.
GPII-187: Fixed the cursor size slider.
There seems to exist a bug though where slider always remembers the
immediately previous saved value.
GPII-187: Added some corrections in magnifierPosition adjuster.
Looks like the composite panel cannot handle "classnameMap" extra
option in sub-panels.
GPII-187: Added expanded headings in "increase size" adjuster.
Some styling will be needed here.
GPII-187: Brought back only the cursorSize in schema.
Corrected cursorSize's heading.
GPII-364: Pulled the highContrast adjuster outside the sliding panel
This is needed in order for it to work inside the composite (for now).
GPII-364: Do not add category styling in (temporarily) pulled out
adjuster container.
