Helper for generating the <title> tag

I don't know about you, but I'm pretty tired of always having to add a helper for generating the "title" tag to my Rails applications. Of course, this could easily be turned into a plugin, but such a small piece of functionality that is so common and essential should really be in the core.

Therefore, I put together a patch that adds a TitleHelper module to ActionView::Helpers containing just a single method called "title". Here is an example:

# Setting the title. For use in <h1> tags, e.g.
title('Welcome')
# => Welcome

title(:site => 'Site')
# => <title>Site - Welcome</title>

Two other options are available:

• separator for defining the separator between site name and title. Default is " - ".
• reverse for reversing the order of site name and title. Default is false, site name first.

Alternatively, the helper could be merged into one of the existing helper modules, e.g. the TagHelper module. Test coverage and documentation should be fine.

Ideas are always welcome. :)
