Service Catalog UI Tweaks

[nwmac]

This PR:

• Adds a subtle flag to the boolean indicator that switches it to use subtler colours than red/green
• Updated service card to use this mode for bindable and active
• Clamped the description to 3 lines with fade for overflow so that all cards are aligned
• Moved service plan count up
• Combined the docs and support links and refined their display
• Improved the service card icon so that if the image fails to load we fall back to the default icon
• Changed line height to 1.5 on the description of the service detail page to make it easier to read

Also:

• Changed the CF Selector view to use the subtle mode and to always show if the user is an administrator of the given CF
