major cleanup of tcsh startup

-	now have initial login and `resrc` doing a "reset"
--		whereas normal startup (eg subshell from vim) doesn't do that
--		anything that takes a significant amount of time is only done on a reset
--		this makes subshell startup _substantially_ faster
-	removed a lot of crap that I never use any more
--		when was the last time I used Sybase? or CVS?
-	removed a duplicate completion for `unsetenv`
add $work's tlib/ to $PERL5LIB
added expand() to myperl
adding in local files from Tyr
a script to paste the clipboard at the command line

this is helpful when the thing you want to paste isn't the middle-click buffer
tweak `vrpt` to have it load another report after all the main buffers
finally fixed the weird intermittent bug where t eats partial output from prove

even though I totally still don't understand why
but, apparently, not piping through Perl makes the problem go away
go figure.
anyway, this also forced me to sacrifice the convenience of detecting when the tested module didn't compile
-	and then running a compile check afterwards
-	but that seems a small price to pay for, you know, getting output
