key entry success msg

[timelsass]

The dismiss notice link should be on a new line positioned more in the bottom left of the notice that popups up for consistency with other notices (like TGMPA's) we use. The padding/margin looks a bit weird on this notice since there's a large amount of whitespace after all the content, this should help balance that out a bit too.

api should be capitalized in this message, but for user feedback of the interaction, the title of the notice should probably change from "Enter Your BoldGrid Connect Key" to "Your BoldGrid Connect Key has been updated!" This will let the user know their action was actually successful (outside of the color change) at a glance.

Then the body of the message should contain the informative bits:
"To change your BoldGrid Connect Key, go to Settings >> BoldGrid Connect in your WordPress dashboard."

Followed with the dismissal link as the 'footer' of the notice.

The phrase should be "Dismiss this notice" instead of "Dismiss Notification" for consistency with TGMPA notices:
