To strip away any HTML. May be useful for the .Title in head etc.
People may shoot themself in the foot with this, maybe ...
The replacement function is pretty fast.
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.

Fixes#1891
This commit fixes a few things:
1. `given` is now a variadic parameter so that piping works properly
2. add separate template tests to make sure piping works
3. support time values
4. add more tests of the dfault function
Add humanize (inflect.Humanize) to the template funcMap. Documentation and
tests are included.
Various code cleanups of the template funcs:
- Break pluralize and singularize out into stand-alone funcs.
- Sort the list of funcMap entries.
- Add some minimal godoc comments to all public funcs.
- Fix some issues found by golint and grind.
* Add meta author, description and generator tags
* Add Hugo version beside the logo and in the footer
* Suggest the user to run `go get -u -v` to update dependencies
* Requires Go 1.3+ rather than Go 1.1+
* Improve rendering/formatting in some places
* Add trailing slash to URLs where appropriate
* GitHub redirects all http requests to https, update accordingly
- Add `safeUrl` template function (Fixes#347)
- Add TestSafeUrl() fashioned after @tatsushid great examples
- Disable `safeHtmlAttr` pending further discussions on its other
use cases because `safeUrl` is a cleaner solution to #347.
(There are also `safeJs` and `safeJsStr` that we could implement
if there are legitimate demands for them.)
- Rename `safeCSS` to `safeCss` (to follow the convention of `safeHtml`)
- Add/expand documentation on `safeHtml`, `safeCss` and `safeUrl`
