make: Create linux-specific install package

Significant change to install process recommendations for Linux.
The provided fonts.conf makes Bitstream Vera the default font
since it doesn't override Emoji One Color. README.md instructions
have been updated to use the provided install.sh.

Fixes #17

+*Warning: This requires `Bitstream Vera` is installed and will change your
+systems default serif, sans-serif and monospace fonts.*
 
-## Install on OS X
+### Why Bitstream Vera
+The default serif, sans-serif and monospace font for most Linux distributions is
+`DejaVu`. `DejaVu` includes a wide range of symbols which override the
+`Emoji One Color` characters. The previous solution was to make
+`Emoji One Color` the default system font, but that causes a number of issues
+*(Check the issue queue.)* A better solution is a different font that doesn't
+override any emoji characters such as `Bitstream Vera`. `Bitstream Vera` is
+the source of the glyphs used in `DejaVu`, so it's not very different.
+
+### Options
+The `Noto` and `Roboto` font families conflict far less than `DejaVu`. You may
+want to try them. Primary issues are the 0x2639 and 0x263a characters.
 
+### Arch Linux
+An AUR is available: https://aur.archlinux.org/packages/emojione-color-font/
+
+## Install on OS X
 There are three install options for OS X. Both SVGinOT versions are available
