[NTG-context] The `\somewhere`-macro

The wiki states on page
http://wiki.contextgarden.net/Latex_Packages#varioref that the macro
`\somewhere` can be used to get same behaviour as varioref gives in LaTeX:

> varioref
> Context provides similar functionality using \somewhere

Some more searching around made me find
http://wiki.contextgarden.net/Command/somewhere

There I can see, that I have to provide 2 text-arguments in curly braces
and the references name in squarebrackets.

So I did exactly that in an experiment.

\somewhere{Foo}{Bar}[foo:bar]

This does create a clickable “Foo” when the reference exists somewhere in
the document, independent off the fact that this reference is on the same
page or anywhere else.

When the reference does not exists, “foo:bar” is typeset.

I am using:

```plain
$ context --version

mtx-context     | ConTeXt Process Management 0.61
mtx-context     |
mtx-context     | main context file:
/usr/local/texlive/2015/texmf-dist/tex/context/base/context.mkiv
mtx-context     | current version: 2015.05.18 12:26
```

Example:

```tex
\setupinteraction[state=start]

\starttext
\startsection[title={Foo-Bar},reference={foo:bar}]
  Blubberblubb, \somewhere{Foo}{Bar}[foo:bar].

  \input knuth

  \somewhere{Foo}{Bar}[foo:bar].
\stopsection

  \somewhere{Foo}{Bar}[foo:bar].
\stopsection
\stoptext
```
