Findbugs 1.3.7 released

Changes :

 Overall, a small bugfix release.
 New detection of accidental vacuous/useless calls to EasyMock methods, and of generic signatures that proclaim the use of unhashable classes in ways that require that they be hashed.
 Eliminate some false positives where we were warning about a useless call (e.g., comparing two incompatible types for equality), but the only thing the code was doing with the result was passing it to assertFalse.
 Japanese localization and manual by K.Hashimoto. (Thanks!)
 Added -exclude and -outputDir command line options to rejarForAnalysis
 Extended -adjustPriorities option to FindBugs analysis textui so that you can modify the priorities of individual bug patterns as well as visitors, and also completely suppress individual bug patterns or visitors.
