bin/import_all: `make schemas/$version/install`: reinstall instead to allow re-running the import to the same custom schema (e.g. 2013-10-18.Brian_Enquist.Canadensys)

bin/import_all: `make schemas/$version/install`: ignore errors if schema exists, to support running with -e

bugfix: bin/import_all: removing inputs/.TNRS/tnrs/tnrs.make.lock: use `"rm" -f` instead of plain "rm" to avoid having an error exit status, which will abort the script if run with the -e flag (as runscripts are)

lib/runscripts/util.run: run script template: changed sample command name to all() because each runscript requires this in order to be run without args

lib/runscripts/util.run: support scripts that are run as shell-includes (with leading "."), by allowing the calling script to manually invoke on_exit() without it then being invoked twice (the end of a shell-include does not trigger the EXIT trap)

bin/*_all: *_main(): renamed to just main() because it does not matter that other shell-includes' main() methods will clobber this, because it is only executed once

bugfix: bin/import_all: Source tables: use .../import instead of import_temp because import_temp is only needed when importing all tables, to prevent the temp suffix from being removed yet

lib/runscripts/util.run: support scripts that are run as shell-includes (with leading "."), by also accepting $@ args that are passed along in the util.run include, in addition to @BASH_ARGV

bugfix: lib/sh/util.sh: alias_append(): need to enclose $(alias) call in "" because its result may contain separator chars (i.e. whitespace) that will be parsed incorrectly. this appears to only be a bug when runscripts are run as shell-includes, with a leading ".".

schemas/VegCore/ERD/VegCore.ERD.mwb: connecting lines: inherits from traceable: added arrow to indicate what this label refers to
