perf ui browser: Make the colors configurable and change the defaults

Just use as a starting point the "[colors]" section of
tools/perf/Documentation/perfconfig.example.

Changed the colors to be the ones in the old perf tool if used in a green on
black xterm.

The next patches should allow using the colors configured for the xterm.
