perf ui browser: Add routines to compactly specify exit keys

Browse Source 
This makes the usual idiom for specifying a series of key codes to exit
ui_browser__run() for specialized processing (search, annotate, etc) or
plain exiting the browser more compact.

It also abstracts away some more libnewt operations. At some point we'll
also replace NEWT_KEY_foo with something that can be mapped to NEWT or,
say, gtk.
