Added edit mode and function to write the changes to file. Write function is not completely done yet because the temp file created by it is not removed when it is done. But other than that the editor actually works now. There are still some quirks that i need to sort out, especially the fact that you cant actually create a new line beyond the amount in the file you are editing
