Update 201309250323

- changed the reset button name to Default Settings
- The reset button will only appear once and only on every page refresh.
The reason is to stop reset spamming.
- added a title on the color field so that users will be able to
identify the hex value
- halfway through: if the color is dark the text should be white and
vice versa
