Fix PHP 5.4 Strict Standards warnings.
Introduce CBox_Bulk_Plugin_Upgrader_Skin::_is_static() method.

This method is used to determine if a class method is called from a
static or object context.

Use this method in the after_updater() method, which can be called in
both static or object contexts.

Fixes previous fatal error when the after_updater() method was called
statically and referencing the class object incorrectly.

Add 'pasteword' button to the visual editor of bbPress.

To add the 'pasteword' button, we have to disable 'teeny' mode in wp_editor().
Also, to emulate the minimal interface of 'teeny' mode, we have to add /
remove a bunch of buttons from the default post editor interface.

Fixes #91.
