Cannot have single entry for "Excluded

[mrl2718]

For the "Excluded" lines, there is no way to have a single entry (with or without text). The following will generate an Error: 0 4 No relevant outcome, 4

The following WILL work - but it is really clunky to be forced to add the second (empty) reason: No relevant outcome, 4; Other, 0

ALSO (separate issue), It would be nice to be able to skip the "Records screened" layer. Sometimes we proceed directly to full-text retrieval and eligibility appraisal.

I've just fixed the single reason bug but it's not yet packaged in a release, you can use the latest version from the main branch here: https://estech.shinyapps.io/PRISMA_flowdiagram_latest/
