Recommend WSL on Windows 10

At this point, I consider the batch scripts @IBNobody and I worked on to mostly be a failure. They've proven to be unreliable, too dependent on the environment they're being run in, and I've seen far too many examples of people having frustrating issues with them that I haven't been able to help them with. They can also produce misleading and confusing error messages. I've been pointing people to use the WSL for a while now. Eventually, I think we should make a proper replacement for the batch scripts, possibly with an environment in msys2. For now, the WSL method in Windows 10 is far more reliable, and is easy to set up. 

I also cleaned up some things in the WSL instructions themselves.

-It's still recommended to use the method for Vista and later below. The reason for this is that the Windows 10 Subsystem for Linux lacks [USB support](https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/13355724-unable-to-access-usb-devices-from-bash), so it's not possible to flash the firmware to the keyboard.

+Due to some issues with the "Windows (Vista and later)" instructions below, we now recommend following these instructions if you use Windows, which will allow you to use the Windows Subsystem for Linux to compile the firmware. If you are not using Windows 10 with the Anniversary Update installed (which came out in July 2016), you will need to use one of the other methods, such as Docker, Vagrant, or the instructions for Vista and later. 
 
-That said, it's still possible to use it for compilation. And recommended, if you need to compile much, since it's much faster than at least Cygwin (which is also supported, but currently lacking documentation). I haven't tried the method below, so I'm unable to tell.
+If you use this method, you will need to use a standalone tool to flash the firmware to the keyboard after you compile it. We recommend the official [QMK Firmware Flasher](https://github.com/jackhumbert/qmk_firmware_flasher/releases). This is because the Windows 10 Subsystem for Linux lacks [libUSB support](https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/13355724-unable-to-access-usb-devices-from-bash), so it can't access the keyboard's microcontroller.

 Here are the steps
 
 1. Install the Windows 10 subsystem for Linux, following [these instructions](http://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/).

+   1. Make sure that you have no changes you haven't committed by running `git status`. ANY UNCOMMITTED CHANGES WILL BE PERMANENTLY LOST.

-4. With the bash open, navigate to your Git checkout. The harddisk can be accessed from `/mnt` for example `/mnt/c` for the `c:\` drive.
+4. With the bash window open, navigate to your copy of the [qmk_firmware repository](https://github.com/jackhumbert/qmk_firmware) using the `cd` command. The harddisks can be accessed from `/mnt/<driveletter>`. For example, your main hard drive (C:) can be accessed by executiing the command `cd /mnt/c`. If your username is John and the qmk_firmware folder is in your Downloads folder, you can move to it with the command `cd /mnt/c/Users/John/Downloads/qmk_firmware`. You can use the Tab key as you go to help you autocomplete the folder names.
 5. Run `sudo util/install_dependencies.sh`.
 6. After a while the installation will finish, and you are good to go
