Dylan Katz 3919a1dcc0 Browser: Load icons at start of program 
Previously, Browser loaded icons from the disk every time an icon
was set. In addition to making more calls to the disk and decoding
more images, this makes error propagation impossible. This change
moves all icon loading to the start of the program.
