faq13.html: add Gnash as Flash plugin option

Now that Gnash is part of OpenBSD 4.1, this diff updates FAQ 13.11
to add Gnash as another option for users who want to use a Flash
plugin with their web browser.

I have also replaced "Macromedia" with "Adobe".

Please feel free to edit/revise my diff.

Thanks,
Lawrence

+OpenBSD provides two options for you to play Flash files.
+You can either use Gnash from the ports tree, or the proprietary Flash
+plugin from Adobe.

+<h3>Using Gnash from ports (for architectures with shared libraries
+only)</h3>
+
+Gnash is a Flash movie player that can be used natively with
+Mozilla-derived browsers such as Firefox.
+It is only available on architectures with shared libraries.
+If your <tt>PKG_PATH</tt> environment variable is set correctly
+(see <a href="faq15.html#Easy">FAQ 15</a>), you can install Gnash
+as follows.
+
+<blockquote><pre>
+# <b>pkg_add -i gnash</b>
+</pre></blockquote>
+
+<p>
+If the Gnash package is installed correctly, the Gnash plugin should be
+listed when you type "about:plugins" in the URL bar of your web browser.
+
+<p>
+<b>Note:</b>
+Gnash is still under heavy development by its authors, and may not work
+with all Flash movies.
+
+<h3>Using the proprietary Flash plugin from Adobe (i386 only)</h3>
+
+The Flash plugin is distributed by Adobe in binary form only.
+Adobe does not provide a native OpenBSD plugin, but there is a Linux
 plugin which you can use under Linux emulation.
 This plugin is available only for the i386 platform.
