Just need to change a few things in boo.g and wsaboo.g,
then edit one line in the not-1.boo test case. These changes are mentioned
in the google note.

Also add a parser roundtrip test that these:
print true and true and true
print true or true or true

are printed out like so:
print (true and true) and true
print (true or true) or true

if there is not already such a test.

I just want to highlight that both C# and Python are in agreement:

C# : false && true || true ==> true
Python : false and true or true ==> true
Python : 0 and 'yes' or 'no' ==> 'no'

Without this fix, boo says that "false and true or true" is false.

Here's a "patch". I wasn't sure how to handle a new file in an anon svn workspace and I put the "svn info" up top. This was authored by Doug H plus I slapped in 2 more test cases.
