Extension:Sternograph

Adds the &lt;sterno> tag to allow easy formatting of plays and interviews, or any other kind of spoken word transcript.

Introduction
Currently on MediaWiki, if one wishes to provide an in-text quote one uses the &lt;blockquote> tag or a template. This is fine for short quotes, but on sites such as WikiMedia or Wikia we don't have such simple quotes. In some cases, we have transcripts of whole scenes with multiple speakers: situations that do not lend themselves well to blockquotes and templates. Currently, one must include a manual of style to demonstrate exactly how to format these transcripts.

The drawbacks to this approach are: Stephen: That's with a P-H. Steven: Wait, am I the same guy from before?
 * Multiple specifications. Changing the formatting for one transcript does not guarantee the change is reflected in all other transcripts.  It's also possible that one speaker's cue is different: for example:
 * Inconsistency. Editors have better things to do than making sure all of the transcripts follow the manual of style.
 * Inconvenience. Repeatedly applying formatting every other line is tedious, even in wiki format.

This is where the Sternograph extension comes in. It provides a new tag, within which one can use wiki-style markup to format the speech, unspoken directions, and even a short context paragraph to come immediately underneath the quote. Formatting of the speakers' names and directions are automatically applied from a CSS file.

Lines
The simplest usage of the sternograph is to include the speaker's name, an = (equals sign) character to separate the speaker from the line, and the ~ (tidle) character to separate different speakers. As in this example:

Release Notes
Beta release! Currently there are only two issues:
 * The CSS stylesheet isn't being applied to the completed Sternograph. This is because I need to find out how to include a new stylesheet in the page.
 * The internationalisation file is there, but the only language is English.
