Updated Styles and moved update all button

Here is what is in this pull request:
I move the Upgrade All button into the title bar for easy access and modified some styling configure it. 
You can see it in attached screen shot. 

NOTES:
I like the tile styling to show each plugin however on my system it shows the buttons like what in the screen shot with the Upgrade Plugin on two lines.  I assume this wasn't by design and it was like this before I started messing with it.  I was going to let you fix it.  :)  Unless you want me to.
