thermo.css: Modified the size of the chart on the daily page to fit the set point values
draw_daily.php: added the setpoint to the graph and, optionally, to the chart
thermo.php: Added the checkbox for the set point temp.  Modified the following text to save space as, in some cases, the right most button, on this line, would wrap.
logs: Added the directory and a small readme to make installation simpler.
