[green] USPS tracking now working

[zackshapiro]

• Completely re-wrote the date method that was the source of many failures. The thing that was causing the error was a hardcoded look for a certain range. With the re-write, it looks for the month in the array and uses it's index as the starting value for the date. It then goes either 2 or 4 places deeper in the array to get the full date based on whether AM or PM is present in that index.
• Re-wrote the description method to detect the description more simply. The format is always a description, followed by a comma, so I'm just splitting on the first comma. Tried this with a few data sets, works well. They never use commas in the description
• Removed excess comma from city, state, zip. They now include it in the city string
• In the location method, detecting whether or not the location is present. If not, returning an empty string for location.
• Was unable to get specs to run, said there were zero specs when that's not true. Rewrote method to be more accurate in detection
• Closes Does USPS require a password? #8
• Still needs tagging update, will leave that to you @travishaynes
