5.0.0

Added a live UI so you can see what the rename operations will look like in real time as you type. You can also get information about each option and replacement variable as well as view the readme without leaving the UI. Simply type rename (or rname) without any arguments to access the UI.

Fixed a bug where rename would enter an infinite loop if you entered a replacement variable that doesn't exist.

Compiled an exe for Windows x64. Unfortunately due to the complexity of the new rename UI, it is not accessible from the compiled exe. I did some very basic testing with the exe but have not fully tested it. I will fix bugs if reported, but am shipping it with the warning that it's not fully tested.
