Fix how "from_community" column is populated

Prior to this commit, the "from_community" column was not providing
accurate data since it was getting the "company" field from a user.

Now it checks if the user is a member of the Puppet Labs organization,
which means that even if the user has not accurately filled out their
"company" field, they will show up as a member of Puppet Labs.
Remove css for graph div

Prior to this commit, there was CSS styling for the div which
contained the community graph which attempted to line up the graph
properly.

Now that styling has been removed as it is no longer needed
to help position the graphs.
