#7 Address Book should not be case-sensative

[Brad Hart]

When addresses are added to the new address book, they
are case-sensative, meaning that if I submit an entry
as "Bobb Fwed" and another as "bobb fwed" I will show
up as two entries.

Instead users should only show up once, no matter how
they capitalize their name.

Should be an easy fix.

Because the system (for greatest optimization) uses PHP's
array_search() function, fixing this would require much
entra code resulting in unoptimization. And seeing as
updating the guestbook could quickly become a long process
with hundreds of posts, this may not be a great idea.

I can do this, so if it is a big priority I'll fix it.
Change the priority to what it should be and change the
resolution to accepted if you want to go through with it.
