--redirect-delay replaced by --javascript-delay in wkhtmltopdf 10

[cfrankct]

Looks like recent versions of wkhtmltopdf don't include --redirect-delay any longer. Seems it has been replaced by --javascript-delay with slightly different semantics. I couldn't find a change-log entry on the wkhtmltopdf site, but the readme says:

--javascript-delay <msec> Wait some milliseconds for javascript finish (default 200) and makes no mention of the redirect-delay any longer. Fix is trivial, line 143 in wicked_pdf.rb becomes:

r +=make_options(options, [ :javascript_delay,

Both are now supported, as of this commit:
