Remove image embed

[Hirse]

The grunt task to embed images was added in 6e58773 when ungit had a lot more images (which were referenced from CSS).

Now, the task only embeds the fonts used by ungit, which is actually counter-productive:

1. The font declaration includes the local()-function so that fonts don't need to be loaded if they are already installed, but this optimization is redundant as the font is embedded in the same file.
   

   ungit/public/less/generic.less

   Lines 12 to 24 in 09232a7

   	@font-face {
   	font-family: 'Open Sans';
   	font-style: normal;
   	font-weight: 400;
   	src: local('Open Sans'), local('OpenSans'), url('../fonts/OpenSans.woff') format('woff');
   	}
   	@font-face {
   	font-family: 'Source Code Pro';
   	font-style: normal;
   	font-weight: 500;
   	src: local('Source Code Pro Medium'), local('SourceCodePro-Medium'), url('../fonts/SourceCodePro-Medium.woff') format('woff');
   	}

2. Bootstrap includes multiple file types of the glyphicon font so the browser can pick their best supported one. By embedding the fonts, all alternatives are served.
   

   ungit/public/vendor/less/bootstrap/glyphicons.less

   Lines 10 to 17 in 09232a7

   	// Import the fonts
   	@font-face {
   	font-family: 'Glyphicons Halflings';
   	src: ~"url('@{icon-font-path}@{icon-font-name}.eot')";
   	src: ~"url('@{icon-font-path}@{icon-font-name}.woff') format('woff')",
   	~"url('@{icon-font-path}@{icon-font-name}.ttf') format('truetype')",
   	~"url('@{icon-font-path}@{icon-font-name}.svg#glyphicons-halflingsregular') format('svg')";
   	}
