Change for rescuetime tracking a category

[kodermike]

The real diff is about line 314-350 (the rest if the compulsive behavior to clean up white space). Not a submissible diff as-is - this just trades out how you were reading a specific activity for tracking a category. I have a version that can use variables from the spreadsheet, but the design decision would be in whether you wanted to have tons of new variables in the spreadsheet (ok....3 or 4, to cover activity vs category, category name, activity name, etc.) or just build the logic for checking all of it in and letting the code sort it out (though you'd still have the problem of user defined names. BAH!).
