-Created pytemp.py Python script to measure and spit out the current CPU and GPU temperatures in degrees C and degrees F to the console
-Now bashwelcometweak.sh will copy over the pytemp.py script to the user's home folder and adds it to the .bashrc to display upon startup
-Now bashwelcometweak.sh also sets the executable flag on ~/pytemp.py for convenience launching from the console
-Newline added where there was none before at pytemp.py EOF
-Rewrote pytemp.py to a pitemp.sh bash script utilizing bc, which is a new requirement (not included on the vanilla Raspbian)
-Added bc prereq install to bashwelcometweak.sh script
-Removed old pytemp.py script
-Integrated simpler bash-only whole-number temperature calculations into .bashrc welcome tweak script, removed requirement for bc and separate file
-Removed pitemp.sh
