bugfix: bin/with_all: isset(): need to use `&>/dev/null` instead of `>&-`, etc because closing an fd causes declare to return false

bugfix: bin/with_all, import_all: don't disown processes because they should be auto-killed if the shell is (disown was only needed before we used screen)

bugfix: bin/with_all: isset(): need to use `>&- 2>&-` because &> does not work with - as the dest

fix: bin/with_all: removed debug statements

bugfix: bin/with_all: testing if @inputs is set: `"${inputs+isset}"` syntax doesn't work for empty arrays, so need to use `declare -p` instead

moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

bugfix: bin/with_all: @inputs default value: use `local`, so that the default value is only set for the current function and doesn't leak back out into the caller. this fixes a bug in subset imports where import_all's Source/import call to with_all would add the .* datasources, but these would then stay in for the import_scrub call, causing extra .* datasources to incorrectly be imported.

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

bin/with_all: $all: renamed to $hidden_srcs for clarity, since this now just adds the hidden (.*) datasources, rather than always using all datasources

bugfix: bin/with_all: in $all mode, just prepend the .* datasources to the user-selected (or default) @inputs, so that using $all to add these datasources doesn't inadvertently cause the action to be performed for all datasources

bin/with_all: added support for providing a custom list of inputs to run the command on

bugfix: bin/with_all: pipe yes to the command in case it makes any interactive prompts, as in e.g. the TNRS staging tables reinstall

with_all: $all mode: Fixed bug where need " " before # for it to be interpreted as a comment (unlike in a Makefile, where the " " often needs to be left out to avoid it being treated as part of a variable value)

with_all: Also exclude .archive/ from the subdirs to forward commands to

with_all: Added $all option to also include datasources starting with . such as .TNRS/. This is necessary for reinstall_all, which needs to install all datasources.

with_all: Support additional command-line args for the make target, such as vars

with_all: Documented that it must be run from the root svn directory

Scripts that are meant to be run in the calling shell: Fixed bug where running the script inside another script would make the script think it was being run as a program, and abort with a usage error

Scripts that are meant to be run in the calling shell: Fixed bug where running the script as a program (without initial ".") wouldn't be able to call return in something that was not a function. Converted all code to a <script_name>_main method so that return would work properly again. Converted all variables to local variables.

Added with_all to run a make target on all inputs at once
