give item logistics shows up on display page
added user name property to item, but instead will add pointer to the actual user
free stuff now has separate view controller to transition to, instead of sharing display vc from myGiveItems
properly initializing the giveItems with the logistics text, and removed back button text from free item vc
decent spacing between collection cells
adjusted some colors app-wide
successfully passing name of item giver to each free item
vertical picture on free item page
black background in front of item image, white text over it— before adopting 3rd party blur
trimmed down giver interface on free item page
adjusted nav bar color to be paler
decent looking round button at the bottom of free stuff list, but going to further adjust it
pretty good looking free stuff page, with giver photo beside item label, although still with hardcoded giverImage
the free stuff vc is now the dominant one in terms of structure and style
