web/: datasources indexed in VegPath: Added .htaccess files to corresponding inputs/ dir so the short URLs can also be accessed via VegBIEN's own dir for the datasource

inputs/input.Makefile: Removed .PRECIOUS from %/header.csv, %/map.csv so that these scripts are deleted on error. This is useful for the runscripts and for non-data dirs whose header.csv cannot be made.

inputs/input.Makefile: SVN: Only run %/add on subdirs with visible (non-hidden) files. Subdirs with only hidden files (e.g. .htaccess) are assumed to be non-data dirs.

inputs/input.Makefile: Staging tables installation: %/install: $(logInstall): Only use log file if log dir exists, to support non-data dirs

inputs/input.Makefile: Staging tables installation: %/install: ignore errors in $(exportHeader) and $(cleanup) if the table does not exist (i.e. a non-data dir)

inputs/input.Makefile: Staging tables installation: %/install: Don't run $(import_install_) for empty dirs because there is no data to import

lib/sql.py: parse_exception(): typed_name_re: Fixed bug where need to require the "" around the table/column name, because otherwise, the regexp will try to match as few characters as possible, causing it to match only the first letter of the name

web/**/.htaccess: Removed "handle DirectoryIndex" rule, which does not appear to be needed with the new dotpath format

web/VegBank/.htaccess: RewriteRule: Fixed bug where need to match tables by themselves as well as followed by columns

web/**/.htaccess: Added "don't rewrite existing paths" and "handle DirectoryIndex" rules to all .htaccess files, not just those for dirs that contain subdirs, to facilitate linking directly to files in the filesystem without first needing to retrofit the applicable .htaccess file.
