comment the roles of the main variables
simplify numify() formatting code

note the difference between '%03d' and '%03s' formats
with regard to leading zeroes
New option: reportproxies
always report proxies
improve the proxy detection

move the proxy detection code to trace_user(), where all the useful
information is still available (instead of trying to get information
when the whole datastructure is already built).

walk the call stack to find something that actually looks like a
subroutine name (by default, Perl uses package::subroutine for
normal subroutines, (eval) for eval. Sub::Name allows changing the
subroutine name, but I expect :: to still be part of the full name:
even 'perl -d:TraceUse -MMoose -MLWP -e1' lists main::BEGIN)
give credit where due
Merge branch 'report-proxies'

Conflicts:
	lib/Devel/TraceUse.pm
whitespace patch: remove all TAB characters

finally!
drop naive spam protection
update test expectations with "possible proxies"
Drop broken numify test
avoid an "uninitialized" warning when no subroutine is found
