using gbrowse 2.13
This causes incorrect link generation in annotation_help and general_help subroutines of Bio::Graphics::Browser2::Render. For example, the "Help -> Help with this Browser" is rendered as "//general_help.html". This is mal-formed and not reachable.
Use of the url_base parameter in Bio::Graphics::Browser2 and Bio::Graphics::Browser2::DataSource appear to be unaffected.
Attached is a simple patch file for Render.pm with the workaround we are using, that returns "/general_help.html" and "/annotation_help.html" if url_base is "/" or default 2.13 behavior otherwise.
