SF 3377279

- Placed JacobVersion.properties into ${release.dir.java.meta.inf} instead of the current folder;
- com/jacob/test/safearray/SafeArrayBasicTest.java is compiled separately, because it is in UTF-16 encoding
- Added initializing Variant used to retrieve the next value from IEnum because some implemenations call VariantClear on it before setting a new value
- Changed _WIN32_WINNT to 0x0500 to fix build with VS2010
- Fixed the leak in Java_com_jacob_com_Variant_putVariantNoParam
- Added Dispatch.Method to the invoke flags to call _NewEnum. There are some nonconforming legacy implementations that expose _NewEnum as a method.
