Can't open an apk if the current directory is not in the same filesystem as the home directory

According to strace, dex2jar outputs into a file in the current directory, which is then moved into ~/.Bytecode-Viewer, but the move fails if the current directory is not on the same filesystem. This failure is silently ignored and results in a FileNotFoundException.

```

Start with JarUtils.java at line 168 and the call from BytecodeViewer.java at line 961, then reproduce the APK-opening flow with the working directory and home directory on different filesystems. Confirm that the generated dex2jar output is available under ~/.Bytecode-Viewer and that opening the APK no longer ends in FileNotFoundException.
