[3.1.0] Implement a few phpt, fix some autoload bugs

- Make our autoload handler polite, ensuring that any __autoload() 
functions get added
- Modify phpt calling code so that each phpt files gets its own 
test-case (this lets us run one phpt file at a time)
- Implement phpt for loading, which test varying loading methods of HTML 
Purifier
- Add --disable-phpt and --only-phpt flags
- More descriptive veto messages, also fix test count
