Creates a new VectorTabs.mustache component and uses it to render
the namespace & view tabs.

Extract SearchComponent.mustache from VectorTemplate. The "search"
message is now escaped by the template parser. As is, htmlspecialchars()
for "wgScript".
A later patch will change each component renderer function as well as
renderNavigation() to return a string.

Regression from 74b9803d9a, caused by a bug in LightNCandy which
caused {{foo}} to render "0", and {{#foo}} to pass as true with "0", but then
in {{#foo}}<b>{{foo}}</b>{{/foo} render as empty string producing "<b></b>".
In other words, the conditional is passing and the inner block is executed,
but the placeholder is mistakenly converting "0" => null => "" (empty string),
causing the <h1> to render but without any text in it.
Work around this bug by simply removing the conditional. Several other skins
already don't have this conditional and it's unclear why or in what
situation MediaWiki would send OutputPage to SkinTemplate without a title.
I think it would make sense in such rare case to still have a consistent
layout for extensions and gadgets to interact with and not omit the H1
element, but render it with the value that OutputPage gave it, even if it
is the empty string.

This reverts commit a3ca2c3e16.
Reason for revert: This requires wider discussion before moving
forward, and a more complete implementation even once we do have
consensus.
No associated task exists on which to view or continue this
discussion: linked task briefly mentions Mustache in general as an
option as part of a much wider topic, but doesn't concern this
specifically.
Issues that should be discussed include:
* What the intent even is here: is this for one skin only? Is this
the intended path forward for all of them? Depending on which, we
have other issues: for the former case, that it is quite
unhelpful in terms of maintenance and further development having
more random code diversity out there, especially in this
half-completed state; or if it is indeed intended for all of them,
that an RfC is needed before anything is merged, as that is a very
significant change.
* That using Mustache in MediaWiki does add (usually minor)
performance overhead; we need to clearly establish in the task that
this is indeed worth it here.
