Subject: [PATCH] Add options to tweak spacegray

Adds italic comment support and the ability to use underline instead of
the highlight search, which makes it much more pleasing to look at, in
my opinion.

Note that the italic comment support in terminal vim requires terminal
support.

 Spacegray is a colorscheme for Vim loosely modeled after
 the [spacegray](https://github.com/zdne/spacegray-xcode) theme for Xcode.
 
+## Options
+
+You can tweak Spacegray by enabling the following disabled options:
+
+1. Underlined Search: Underline search text instead of using highlight color.
+   Put the following in your `~/.vimrc` to enable it:
+
+  > `let g:spacegray_underline_search = 1`
+
+2. Italic Comments: Italicize comments (_note_: vim requires terminal support).
+   Put the following in your `~/.vimrc` to enable it:
+
+  > `let g:spacegray_italicize_comments = 1`
