File Splitter v1.0

This will split a into parts of the given size. I know that there are a lot of these on psc (and other sites), but the code here is clean, neat and very well commented and keep in mind that this is for learning purposes. Good for anyone learning about file/string handling. The gui isn't up to much, but the code is centered around a module, so you can just add the module into another project and call the functions. You only need three things to use the module, a form, a label and a progressbar. The interface is entirly up to you. All checks are done internally, so the interface code is about as minimal as you can want. Any suggestions for improvements are welcome and feel free to vote :)
