Checker Framework 1.9.3

Version 1.9.3, 1 July 2015

New command-line options:

• -AsafeDefaultsForUnannotatedBytecode causes a checker to use conservative
  defaults for .class files that were compiled without running the given
  checker. Without this option, type-checking is unsound (that is, there
  might be errors at run time even though the checker issues no warnings).
• -AuseConservativeDefaultsForUnannotatedSourceCode uses conservative
  annotations for unannotated type uses. Use this when compiling a library in
  which some but not all classes are annotated.

Various bug fixes and documentation improvements.
