Move files by only changing pointer data if both paths are in the same partition

[booth-w]

The part you want enhanced
In other tools like gnu mv or the nemo file manager, if you move a file/directory within the same partition, instead of copying the file contents on the drive and then removing the original, it creates a new directory entry pointing to the same inode as the original.

Why it is necessary to enhance
When moving large files, it currently uses an unnecessary amount of I/O operations and can be substantially sped up to be almost instantaneous.
