Add a new rssLimit site configuration option with default of 15. Prior
to this fix, you could create your own RSS feed to override the default
limit of 15, but we still had a hardcoded limit of 50 items set in
`hugolib.renderRSS()`.
With this option in place, the `range first 15 .Data.Pages` logic is no
longer hardcoded into the embedded RSS template.
Because the size of the slice passed to the template is now limited to
rssLimit instead of 50, this commit is a breaking change for sites
with a custom RSS template that expects more than 15 items.
Fixes#3035
All config variables starts with low-case and uses camelCase.
If there is abbreviation at the beginning of the name, the whole
abbreviation will be written in low-case.
If there is abbreviation at the end of the name, the
whole abbreviation will be written in upper-case.
For example, rssURI.
Meny people, including me, have a custom robots.txt in static.
Also remove that option from the command line; it doesn't feel
important enough.
Fixes ##2049
This disables highlighting for fenced code blocks without explicitly specified language. It also introduces a new `PygmentsCodeFencesGuessSyntax` config option (defaulting to false).
To enable syntax guessing again, add the following to your config file: `PygmentsCodeFencesGuessSyntax = true`
This is a breaking change.
This uses the Emoji map from https://github.com/kyokomi/emoji -- but with a custom replacement implementation.
The built-in are fine for most use cases, but in Hugo we do care about pure speed.
The benchmarks below are skewed in Hugo's direction as the source and result is a byte slice,
Kyokomi's implementation works best with strings.
Curious: The easy-to-use `strings.Replacer` is also plenty fast.

Also add a note saying that these blackfriday flags are
very case-sensitive as of Hugo v0.15.
Thanks to @ryanclarke for noticing the change in behaviour.

To allow the end users to disable any form of smart dashes
(LaTeX-style or not) while keeping the rest of Blackfriday
SmartyPants features.
Depends on https://github.com/russross/blackfriday/pull/190
"Add HTML_SMARTYPANTS_DASHES for toggling smart dashes"
to be accepted by Blackfriday developers.
