classPattern directive, allowInInstanceOf wildcards, param conditions in more places

New

• classPattern param directive matches a parameter's declared class name against a wildcard pattern using fnmatch() (#412, docs example #417)
• allowInInstanceOf/disallowInInstanceOf now support fnmatch() wildcard patterns (#399, docs example #417) and param conditions (#401)
• Param conditions also work with allowExceptIn/allowExceptInMethods and their disallowIn* aliases (#414)
• allowExceptParamsAnywhere and disallowParamsAnywhere aliases for allowExceptParams/disallowParams to match other *Anywhere directives (#410)

Bugfixes

• typeString: descriptive exception on parse failure (#407)
• Empty string in typeString now throws an exception, and '0' (a string consisting of 0) is now a valid typeString (#409)
• First-class callable syntax (func(...)) with param conditions is now handled correctly (#418)
• allowExceptInFunctions/allowExceptInMethods with multiple entries only checked the first one, not anymore (#405)
