Circ Stats - Remove spaces from uploaded file name

[matthewahmed]

This can wait until Circ Stats Report is already being updated for something else.

If an uploaded barcode list has any spaces in its file name, replace them with underscores when saving to /s/SUL/Dataload/Uploads/CircStats . Same as with prefixing the name with the SUNet ID, the no-spaces name should also be used when deriving the OUTPUT_NAME value for the CIRC_STATS_RPT_LOG table.

For example if a user uploads "my barcodes.txt", it should be saved as "sunetid_my_barcodes.txt".

The PL/SQL nightly processing currently has a workaround for handling filenames with spaces. However it's a confusing kludge that should be removed when possible.
