- Created a base class (TextDiagnostics) for all text diagnostic classes.
  Moved the "IgnoreDiagnostic" method up there, and created a method that
  will format the diagnostic string, replacing %# with the appropriate
  string. This is in preparation for adding a text diagnostic checker.

Fixed typechecking bugs wrt UsualUnaryConversions. Includes two distinct fixes:

#1: Call UsualUnaryConversions in CheckRelationalOperands/CheckEqualityOperands.
#2: UsualArithmeticConversions arguments are now output parameters. This insures
the implicit conversion is seen by clients (and fixes bugs in CheckAdditionOperands
and CheckSubtractionOperands when doing pointer arithmetic).

- Added a method "IgnoreDiagnostic" so that the diagnostic client can
  tell the diagnostic object that it doesn't want to handle a particular
  diagnostic message. In which case, it won't be counted as either a
  diagnostic or error.
