[turba] Firstname/Lastname display problem

[David Ross]

Here's one of those cases why getting rid of the "Name" field and going 
with separate First and Last is much better.

Using Turba 1.2.  If the "Name" field has a comma (',') in it, and you 
set your Display preferences to "Firstname Lastname", the code in 
lib/Turba.php breaks and *nothing* gets displayed!

There are two if statements and one uses the strlen() function and the 
other uses String::length().  It appears String::length() doesn't 
work/exist (for me, anyway).  Changing the second if to use strlen() 
instead fixes my problem...
