Done this way we can actually traverse the objdump_line objects directly, matching the addresses to the collected samples and colouring them appropriately using lower level slang routines. The new ui_browser class will be reused for the main, callchain aware, histogram browser, when it will be made generic and don't assume that the objects are always instances of the objdump_line class maintained using list_heads.
