    [branch-0.7] Minor styling for Helium menu

    ### What is this PR for?
    Since Helium online registry is available in develop 
version(0.8.0-SNAPSHOT) for now, people only can use their local registry(e.g. 
`ZEPPELIN_HOME/helium`) in 0.7.X. So they will see below empty screen when open 
Helium menu at the first time.

    It's hard to recognize what Helium is and not that attractive actually.
    
    So I added 
     - initial sentence "Currently there is no available package to be listed" 
when there is no package under local registry
     - question icon to header -> link to 
https://zeppelin.apache.org/helium_packages.html to give some hint(?) about 
Helium :)
    
    And also fixed `VISUALIZATION` button group as I did in #2185.
    Please see below screenshot images for the details.
