Title: Added support for reserving memory

HI, I'm using SDWebImage with UITableView. With at most 6 visible images at one time. The tableView contains 100 images. Each image is has an original resolution of 1024*768. I found my app often killed on iPad 1st gen, when scrolled fast.
Log showed number of objects in memCache increasing all the time, and the app was killed even before it received any memory warning.
So I added support for reserving memory, and my app no longer crash on iPad 1st gen.
