Bug in Crawlers spelling in browsers.c

[junelac]

Hi,

I noticed by chance 2 spelling mistakes in browsers.c (main branch)

  {"ZoteroTranslationServer", "Cralwers"},
  {"OAI-SearchBot", "Cralwers"},

I don't know if it affects anything but I thought I should inform you

Thanks very much! Pushed a fix for this.
