get_help_uri

Gets the help URI of the plugin.

The Help URI of a plugin will typically be presented by the plugin manager as a "Help" button linking to the URI. It can either be a HTTP URL on some website or a ghelp: URI if a Gnome help page is available for the plugin.

The relevant key in the plugin info file is "Help". Other platform-specific keys exist for platform-specific help files. Those are "Help-GNOME", "Help-Windows" and "Help-MacOS-X".

Parameters:

this	A PluginInfo.

Returns:

the plugin's help URI.
