Added an additional step in the reflow process to verify whether the temperature probe has been set on the PCB.
Fixed syntax and compile errors. Updated to rev. 1.3.
Fixed issues with adding the additional probe routine. Will work on exiting a reflow and an odd issue where the PID loop runs after completion and attempts to keep the temperature at 49C.
Experimental code adding enums and other mode tracking. Also attempting to integrate a variable reset whenever the COMPLETE mode runs. Code will not compile and is complaining about variables.

Added a countdown to start reflow, fixed a bug where the oven keeps wanting to approach 50C after reflow, adjusted PID values, added asthetics to LCD, improved push button response, cleaned up comments.
