TwitterLib/Witty crashes on malformed Xml from Twitter

[GoogleCodeExporter]

1.  Run Witty when twitter is having difficulties.

Using 1.6 beta, downloaded today.  After spitting back server 500 errors, 
twitter stabilized around 4:10AM EST.  After another 5 or 6 minutes, it 
was doing an update and the doc.Load(reader) line threw XmlException.

Given the recent trouble, I think a TwitterProblemsException might be a 
good idea, given that theres already a RateLimitException.

Full Error From VS.NET 2008 Debugger:

System.Xml.XmlException was unhandled by user code
  Message="Data at the root level is invalid. Line 1, position 1."
  Source="System.Xml"

twitter is undergoing some backend changes that's killing twitter api 
reliability.
I'm going to sit on this for a day or two for the twitter servers to be 
stabilizes. 
If it doesn't then I'll look into contingency plans for malformed xml from 
twitter.

Great idea about the TwitterProblemsException.

Twitter API has stabilized in the past year. Closing.
