windows: Add windows install package

Adds an install process to replace Emoji on Windows.
It merges the EmojiOne font with Segoe UI Symbol on the user's machine,
and replaces Segoe UI Emoji as well on Win 8 and 10.

An uninstall script is also included to assist the user in restoring
the original Windows fonts.

README also updated.

Fixes #15

 ## Install on Windows
 
-The font installs like any other font and can be specifically selected, but
-the system will default to the `Segoe UI Emoji` font. Get the current version
-from: https://github.com/eosrei/emojione-color-font/releases
+There are two install options for Windows. Both SVGinOT versions are available
+from releases: https://github.com/eosrei/emojione-color-font/releases

+will default to the `Segoe UI Emoji` font for emojis.
+
+### Replacing the Windows default Emoji
 
-Help wanted: [How to override the Windows default Segoe UI Emoji font][16]
+Because Windows 7, 8, 10 use Emoji in both Segoe UI Symbol and Segoe UI Emoji,
+to be the default emoji, we need to replace both, but keep the existing symbol
+characters from Segoe UI Symbol. 
+This package contains an install script that will generate both fonts (or
+in Windows 7, just Segoe UI Symbol), and install them for you. Running the
+install script requires both [Python][16] and pip in the PATH.
 
-[16]:https://github.com/eosrei/emojione-color-font/issues/15
+1. Download the most recent Python 3 for Windows: https://www.python.org/downloads/windows/
+2. Start the installer, select "Add Python 3.5 to PATH" and finish the install process.
+3. Download EmojiOne Color Windows package from releases:
+   https://github.com/eosrei/emojione-color-font/releases
+4. Uncompress the file
+5. Open the new EmojiOneColor directory
+7. Run install.cmd. Note: This will take some time.
+8. Install the new fonts when requested.
+9. Done!
+

+
+*Reiterating: Only FireFox supports the SVGinOT color emoji for now. IE and
+Chrome will use the fallback black and white emoji.*
