Set default font colour of certain JQM classes to black in base SCSS. Prevents JQM from changing default colour from black to dark grey when JS is enabled.
Changed content body text colours from dark grey to black for all applicable swatches in JQM theme SCSS. Also removed JQM body text colour override from base SCSS.
Restored double exclamation marks (!!) in JQM themes. Prevents JQM license headers from getting stripped when building.
