Modify the API in Advapi32Util for support registryGetKey() in WOW64 flag

[Falldog]

For Advapi32Util support the WOW64 flag
reuse the current API registryGetKey() to open the WOW64 flag

Ex:
HKEYByReference phkKey = registryGetKey(WinReg.HKEY_CURRENT_USER, "Software\JNA", WinNT.KEY_READ | WinNT.KEY_WOW64_32KEY);
String value = registryGetKeys(phkKey.getValue(), 'StringKey');
registryCloseKey(phkKey.getValue());

On UnitTest,
I think original testcase would include the new API testing

BTW, I think this may fit the feature request #101

I think this is worth fixing/implementing, but I am not sure this is the best way.

My first reaction was whether those new methods that take an HKEY should be private? The util library tries to help you with management of handles, you should in theory not have to worry about those. The new method violates that principle.

If that's the case, you could expose a registryGetValue64?

What do you think?

Please also update CHANGELOG. Thank you.

I think this way would be more general, and expose less API
first,
for x86 application call registryGetXXXValue() default would get x86 value,
and it should set the flag as KEY_WOW64_64KEY to read x64 key path
for x64 application call registryGetXXXValue() default would get x64 value
and it should set the flag as KEY_WOW64_32KEY to read x86 key path
I think add registryGetValue86(), registryGetValue64() is not a good idea

Unfortunately, check that registryGetValue() would use the windows API RegGetValue()
reference : http://msdn.microsoft.com/en-us/library/windows/desktop/ms724868(v=vs.85).aspx
this API could not specific to read/write on KEY_WOW64_32KEY or KEY_WOW64_64KEY

So, maybe this way would like registrySetXXXValue() to access opened HKEY directly.

What do you think?
If these is better way, I would like to modify it
Thank you.

Thought about this a bit, and I think I agree that what you wrote is the best of the solutions. Can you please update CHANGELOG and I'll merge this? Thx.

Merged, sorry for the delay.
