Bug Fixes and New Features

-Fixed various bugs with the keyboard input (broken shift key, and some
other small changes).
-Fixed a bug with the memory, registers, and other components not being
cleared when running a new file.
-Various other small bug fixes.
-Updated how text is displayed.  Now properties of text inputs are
displayed on the top screen where you type as well, so you don't have to
look between screens.
-Added a text editor to the application!  Currently it only supports
creating new files, though I may add the ability to edit old files as
well.
-Added new screenshots to the build.
-Rebuilt and repackaged into the RAR archive.
