Snippets: do not render snippets from template which is included using includeblock macro

[matej21]

• fixes block defined in includeblock template included in snippet doesn't exist for ajax redrawing nette#1510

[matej21]

But there is an inconsistency I don't like (It was NOT introduced by this commit)
compiled template may look like this:

if (empty($_l->extends) && !empty($_control->snippetMode) && empty($_g->includingBlock)) {
    return Nette\Bridges\ApplicationLatte\UIMacros::renderSnippets($_control, $_b, get_defined_vars());
}

// !!!!! including blocks...

<?php if ($_l->extends) { ob_end_clean(); return $template->renderChildTemplate($_l->extends, get_defined_vars()); }
call_user_func(reset($_b->blocks['content']), $_b, get_defined_vars()) ; 

so in snippet mode, if template has no layout, blocks won't be included at all.

Is it BC break?

@matej21 please can you rebase it, I'll merge it

[matej21]

rebased (it is failing because the test depends on nette/latte#34)

Is it BC break?

I hope it is not :)
