We should have proper formatting for bacterial nomenclature

[phet-steele]

@aadish we should do one of two things for the "Real Cells" image caption. In either case, we should italicize E. coli AND make "coli" lowercase. I see the options we have being:

1). Italicize, lower case and stop there, results in: E. coli.
2). Italicize, lower case, and do not use the abbreviation, results in: Escherichia coli.

I believe option 2 is more proper since it's the first and only time in the sim we refer to the bacteria by name. However, I'm okay with option 1 if we do not have room for such a long string. @aadish, can you try to fit in option 2 first and we go from there?

For phetsims/tasks/issues/776.

@phet-steele I pushed changes to reflect option 2 take a look at master and let me know how does it look and any other changes required

@aadish Hooray we have room! Thanks! Two things to note:

• We lost the period at the end of the first sentence, after (GFP).
• Can we get rid of the space between the first and second lines? (Highlighted with the red box)

@phet-steele pushed changes let me know how it looks now

The latest still has a slight gap between the first and second lines. This may be a result of different font sizes being used in each line. @aadish is investigating. Here is the latest:

@phet-steele let me know how it looks just pushed the changes
