Bug 11920: Web Inspector should have Firebug-like CSS editing
​http://bugs.webkit.org/show_bug.cgi?id=11920

• css/CSSComputedStyleDeclaration.h: (WebCore::CSSComputedStyleDeclaration::isPropertyImplicit): Return false. I'm not sure why this was true, but computed style has no concept of implicit. So false makes more sense and makes the code simpler in the inspector. This function was added for the inspector, so this isn't a compatibility change.
• page/inspector/PropertiesSection.js: Add a getter/setter to reset populated status.
• page/inspector/StylesSidebarPane.js: Some refactoring along with the main support for style editing.
• page/inspector/inspector.css: Style changes for propery editing and focus correctness.
• page/inspector/inspector.js: Look for a handleKeyEvent function of the focus element before trying to call a function based on the element's id. Call focused and blurred on the focused element when currentFocusElement is changed. Use the new listItemElement getter instead of the private property.
• page/inspector/treeoutline.js: No longer expand on double click if ondblclick is implemented. Shrink the toggle zone to 10px to better match the size of the arrow. Add an onattach call to allow generation of the title using the DOM element. Add listItemElement and childrenListElement getters.
• page/inspector/utilities.js: Add new helper prototype methods on CSSStyleDeclaration.
• page/inspector/DocumentPanel.js: Use the new listItemElement getter instead of the private property. Also expand the DOM node on double click now that the TreeOutline dosen't do it.
• page/inspector/Resource.js: Use the new listItemElement and childrenListElement getters instead of the private properties.
