Title: enable blocks in EGOImageLoading using prefix definition

EGOImageLoader offers use of blocks, but only if a particular constant is defined (__EGOIL_USE_BLOCKS):
https://github.com/enormego/EGOImageLoading/blob/master/EGOImageLoader/EGOImageLoader.m#L182-225

Prior to using cocoapods, this definition was easily enough set in one's project prefix file. Integrated as a cocoapod, though, the definition must exist in Pods-prefix.pch
