*SVN*
* Added caching option to AssetTagHelper#stylesheet_link_tag and AssetTagHelper#javascript_include_tag [DHH]. Examples:
stylesheet_link_tag :all, :cache => true # when ActionController::Base.perform_caching is false =>
<link href="/stylesheets/style1.css" media="screen" rel="Stylesheet" type="text/css" />
<link href="/stylesheets/styleB.css" media="screen" rel="Stylesheet" type="text/css" />
<link href="/stylesheets/styleX2.css" media="screen" rel="Stylesheet" type="text/css" />
stylesheet_link_tag :all, :cache => true # when ActionController::Base.perform_caching is true =>
<link href="/stylesheets/all.css" media="screen" rel="Stylesheet" type="text/css" />
...when caching is on, all.css is the concatenation of style1.css, styleB.css, and styleX2.css.
Same deal for JavaScripts.
* Work around the two connection per host browser limit: use asset%d.myapp.com to distribute asset requests among asset[0123].myapp.com. Use a DNS wildcard or CNAMEs to map these hosts to your asset server. See http://www.die.net/musings/page_load_time/ for background. [Jeremy Kemper]
* Added default mime type for CSS (Mime::CSS) [DHH]
