[FEATURE] Multi-sections support

[gbwebdev]

Add support for multiple sections

For my personal use, I made a few changes to the FeelIt Theme to support multiple sections :

• The home page displays summary cards of all sections together.
• A menu entry is created for each section :
  • It redirects to the section's index page
  • It is higlighted whenever you are visiting the section index or a section's post.
• The section's index pages displays a list of all the posts in said section :
  • As a timeline (by default)
  • As summary cards (by setting params>sections>displayAs to cards)
• Catagories can be grouped by sections (by setting params>taxonomies>groupCategoriesBySections to true)
• Tags can also be grouped by sections, but things get more complicated...
  • You have to create a new taxonomy named tag_<section_name> for each section by adding this to taxonomies :

    tag_<section_name>: tags_<section_name>

  • You have to use the right taxonomy for each section.
  • You have to set params>taxonomies>groupTagsBySections to true

If you are interesed, I would be glad to commit my work. You might want to double check as I am quite new to both Golang and Hugo environment...
