libwps/libwps.msvc.warnings.patch

+fix MSVC warnings:
+
+* various C4946 reinterpret_cast between related classes
+* silly C4305 truncation from double to float
+* C4806: no value of type 'bool' promoted to type 'int'
+  can equal the given constant (real bug?)
+* C4701: pot. uninitialized variable 'ucs4Character'
