/Makefile: python-Linux: removed no longer used installation of pp (Parallel Python). we use Python's multiprocessing package instead.

bugfix: /Makefile: install: must be config/download/live, not config/download

README.TXT: bin/sync_upload calls as root: don't need to set $USER because this is now set to the correct value in bin/sync_upload's scripts

bugfix: lib/sh/local.sh: $sync_remote_url: jupiter user is always aaronmk, not the local user

*{.sh,run}: use standard WARNING syntax for warning labels

bugfix: /Makefile: bin/install: also need to install uutils

*{.sh,run}: use standard WARNING syntax for warning labels

fix: lib/sh/util.sh: verbosity_compat(): documented that this should not be run until right before executing an external command, so that it doesn't mess up the logging mechanism

bugfix: bin/make: don't run verbosity_compat until right before executing the external command, so that it doesn't mess up the logging mechanism. this is run automatically by command(), so there is no need to do anything here. note that logging bugs like these can now be troubleshooted much more easily with pst() to narrow down which functions could be causing the problem.

bugfix: lib/sh/util.sh: functions called by pst(): commented out/removed logging calls that would have caused infinite recursion when pst()'ing a logging function
