Bugfix for HTitle. Again
Replace solid color to gradient in #window-controls border
Replace settings to options; move css files from content/ to skin/; rename something

1. Because "options.xul" is the default name for inline options.

   https://developer.mozilla.org/en-US/Add-ons/Inline_Options

2. Skin is more correct place for our stylesheets.

3. Like "nodes" to "elements", "attribute" to "attributeName".

   No any important.
