Plugin Install Scripts

[dkobia]

• Allows plugins to include install scripts that are run when the plugin is activated see Plugin Install Scripts #222
• The plugin registers an installer callback
• Added a footer plugin hook

Example init.php:

class Webanalytics_Init {

    public function __construct() 
    {
        // Register an installer
        Swiftriver_Plugins::register('webanalytics', array(new Webanalytics_Install(), 'db'));
    }
}

Example Callback:

class Webanalytics_Install {

    public function db()
    {

    }
}

Exception handling (and logging) where execution of the callback is unsuccessful.

I also think the return value should be of type bool as opposed to void - for convenience of writing a unit test for this method

I think we should have a plugin_installed column in the plugins table so that we don't call Swiftriver_Plugins::install() each time the plugin is enabled.

Adding on to keeping track of plugins that are installed, I would suggest rather than automatically installing on enable, the plugin must be installed before being enabled. Put an "Install" button where the enable checkbox is if the plugin has yet to be installed. This would allow plugins to have a graphical install for configuration options if they chose to.

Added exception handling and plugin_installed column. @Deathshiver, I think adding an extra install step during plugin installation complicates things slightly. I'm leaning more to this approach until we have an install that requires configuration options.
