1.2 Update

Changed the file size counter, now it show an aproximation of the file size when you make any change. Because I didn't want to add just that, I added some more functions, I added the options to go to the bottom or the top of the file. And I added the function for duplicating the current line

Thanks for reading, and I appreciate any feedback.
At this point the program It's almost finished, im not sure if I'll add more stuff, the only thing that I got in mind is adding the option to open and edit multiple files at the same time, so any ideas or suggestions help. Thanks, again.
