added bin/sync_upload, a wrapper around sync_upload()

bugfix: lib/sh/sync.sh: upload(): only add `--exclude="**"` if there are --includes. this enables running upload() without paths to upload all files.

lib/sh/sync.sh: upload(): support passing -- options to put, which will not be run through the path->--include processing

bugfix: lib/sh/sync.sh: upload(): added missing `local args=()` initializer

/README.TXT: Full database import: On local machine: added step to do steps under Maintenance > "to synchronize vegbiendev, jupiter, and your local machine", which is needed in addition to `make inputs/upload` since that doesn't handle overwrites or deletions

/README.TXT: Maintenance: to synchronize vegbiendev, jupiter, and your local machine: added warning that you should pay careful attention to all files that will be deleted or overwritten (as the three machines are often out of sync)

added inputs/GBIF/_MySQL/GBIFPortalDB-2013-02-20.data.0.preamble.sql

/README.TXT: Full database import: make inputs/{upload,download}: run them first with `test=1` to see what the changes will be

/README.TXT: Full database import: `svn up`: use --force to avoid errors about existing files

mappings/VegCore-VegBIEN.csv: genus->taxonlabel.taxonomicname: filter out genera that contain numbers (using new _filter_genus()), which break TNRS and prevent it from matching any other parts of the name. later, these genera can instead be moved to the end of the name, where TNRS will correctly match them as Unmatched_terms.
