  Make path to "private.json" relative to script location
Readme update to reflect ciex's (Vincent Ahrend's) changes that allow the script to be run from anywhere.
Fixed bug in date detection for the title of the -g plot. The bug was due to time.ctime() padding left with an extra space for single-digit dates, resulting in my .split(" ") adding an empty string element to the list.
Fixed graphing to work when the week spans a month-month boundary.
Also changed the x-axis labels to be day name abbreviations rather than date numbers.
