Update display speeds and rounding

Adds the following modes for display update:
Fast (old style)
Slow (1Hz)
Rounded (Only shows to 10C increments)
None (No temp, just symbol)

-The bootloader does not appear to work under mac or linux at the moment.**
+Officially the bootloader on the iron only works under windows. However, users have reported that it does work under Mac, and can be made to work under Linux. Details over on the [wiki page](https://github.com/Ralim/ts100/wiki/Upgrading-Firmware).
 
 1. Hold the button closest to the tip, and plug in the USB to the computer.
 2. The unit will appear as a USB drive.
 3. Drag the .hex file onto the USB drive.
 4. The unit will disconnect and reconnect.

 # Version Changes:
+
+V1.09
+- Adds display modes, for slowing down or simplifying the display
+
+V1.08
+- Fix settings menu not showing flip display
+
+V1.07
+- Adds shutdown time to automatically shutdown the iron after inactivity
+
 V1.06
 - Changes H and C when the iron is heating to the minidso chevron like images
