The following option has been added to `params.toml` to control related content on pages:
`show_related = {docs = true, page = false, post = true, project = true, publication = true, talk = true}`
When `summary` is defined, the full summary text is now shown in listings.
Add `summaryLength = 30` (length in words) to `config.toml` to customise automatic summaries from using `<!--more-->` tag or full content (when `summary` and `abstract` are not defined).
Add `abstract_length = 135` (length in characters) to `params.toml` to customise truncation when `abstract` is used as the summary.
