Revisit <br> injection in get_sitename_formatted()

[cjg89]

I think we could potentially re-add the <br> insertion that was removed in the commit below if we tried doing a substring length check on the chunk of the college name after "of".

e.g. for "College of Business", if the portion of the name after "of " ("Business") is greater than a certain number of characters (~15 maybe?), insert the <br>.

It would help us catch college names with longer names that don't have an ampersand, such as "Rosen College of Hospitality Management", but avoid inserting it in cases where the college name is not very long, like "College of Business" and "College of Sciences".
