Experimentation here: naming "ui_something" we may be treading into creating a TUI/GUI set of routines that can then be implemented in terms of multiple backends. Also the time it takes for adding things to the "browser" takes, visually (I guess I should do some profiling here ;-) ), more time than for processing the events... That means we probably need to create a custom hist_entry browser, so that we reuse the structures we have in place instead of duplicating them in newt.

This allows us to remove the use_browser checking in the color_printf routines, that now got color_snprintf variants too. The newt TUI browser (and other GUIs that may come in the future) don't have to worry about stdio specific stuff in the strings they get from the se->snprintf routines and instead use whatever means to do the equivalent. Also the newt TUI browser don't have to use the fmemopen() hack, instead it can use the se->snprintf routines directly. For now tho use the hist_entry__snprintf routine to reduce the patch size.
