Added a Toggle button to the palette, to show/hide the picker area. Including updated docs and example with new options.
Bugfix: Forgot one semicolon.
Several changes after comments from bgrins. WARNING: option variable changed

- Changed showPaletteOnlyToggle to togglePaletteOnly (be sure to change it everywhere you used it).
- Removed test for toggleLessText to be a string, this fixes a bug and improves readability.
- Cleaned up CSS -> open brackets on the same line as the selector.
- Cleaned up de docs -> removed separate toggleText and toggleLessText topics and added some extra text to togglePaletteOnly.
Added comment for explaining moving the palette to the left. Added Unit-test for the Toggle Button.
Changed text-options to 'togglePaletteMoreText' and 'togglePaletteLessText'. Fixed some tabs/spaces.
Merge branch 'showhidepicker'
