Improvements to property display styles in Saga View

[HEskandari]

There are a few issues with the way property key / values are displayed in SagaView so the following improvements should be made:

• Contrast for property names and values is to be increased while keeping special characters de-emphasized.
• Show the active tab in underlined black text to indicate it's active and can't be clicked again.
• Mouse cursor should change to Hand when hovering over the links.
• In order to not have View properties: displaying as if it was another property and better align the display of custom tabs with SP, change tabs labels, reduce font size by 2pt and make it all caps.

This was done as a part of #648 but we're moving the relevant parts here and only keep the bug / issue in 648.

@sergioc The screenshot above only shows black color for the selected underlined text. What color should be the 'underline' part when you hover over the not-selected text? In other words, should it behave link other links e.g. link to (xxx bytes)?

@HEskandari I guess the hover style for a link should continue to be a blue underline. A black underline would look very strange.

Same blue as the link.
