4f66f790b1 Add readFile template func
This also includes a refactor of the hugofs package and its usage.

The motivation for that is:

The Afero filesystems are brilliant. Hugo's way of adding a dozen of global variables for the different filesystems was a mistake. In readFile (and also in some other places in Hugo today) we need a way to restrict the access inside the working dir. We could use ioutil.ReadFile and implement the path checking, checking the base path and the dots ("..") etc. But it is obviously better to use an Afero BasePathFs combined witha ReadOnlyFs. We could create a use-once-filesystem and handle the initialization ourselves, but since this is also useful to others and the initialization depends on some other global state (which would mean to create a new file system on every invocation), we might as well do it properly and encapsulate the predefined set of filesystems. This change also leads the way, if needed, to encapsulate the file systems in a struct, making it possible to have several file system sets in action at once (parallel multilanguage site building? With Moore's law and all...)

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.

df44b1930a tpl: Send actual values to in from intersect
The `intersect` function uses `in` to avoid adding duplicates to the
resulting set.  We were passing `reflect.Value` items when we should
have been using `Value.Interface()` to send the actual data structure.
This fixes that.

See #1952

b0326a1c0f tpl: Treat booleans as set in default function
Booleans and `default` don't really make sense together, so we'll always treat
booleans as "set" and return the given value.

cafb784799 Add emoji support
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.

2d0650dbd9 tpl: Add custom index function
This commit adds a custom index template function that deviates from the stdlib
simply by not returning an "index out of range" error if an array, slice or
string index is out of range.  Instead, we just return nil values.  This should
help make the new default function more useful for Hugo users.

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

5995eaaa08 tpl: Unexport all template funcs
There is no good reason to export all the template funcs:

* They're not used outside the templates.
* If usable in other packages, they should be moved (to helpers?)
* They create too broad an interface;
  users of the tpl package don't see the forest for all the trees.
