Allows caption shortcode to have shortcodes
The core img_caption_shortcode()
function doesn’t process shortcodes when they’re in the caption (just when they’re in the image). This simple plugin changes it so that captions can contain shortcodes.
It also fixes some other small edge-case bugs in the original code.

Once installed and activated, there’s nothing more you need to do (though you
can use filters in your themes functions.php
to change the behaviors)
Just activate the plugin.
