Support for saving docx
Apache OpenOffice in PC version is not supported saving docx, but AndrOpen Office is supported it now.
Apache OpenOffice has saving docx functionality but it is disabled and the source code is little old.
I refresh the old source code and enable to save docx.
I have plans to support to save xlsx and pptx format in the future version, too.
Fix for Android 6.0
Some native functions are changed in Android 6.0. (i.e. dlopen)
So, it was necessary to change programs for it, and I fix it.
