function swftools_admin_extensions_submit in SWF Tools 6.3

Explodes a string of file extensions and converts them back in to an array.

On the admin page we show the user a list of actions and allow them to associate extensions with each one. But when it comes to generating content we will have the extension and we need to discover the action.

What we do in this submit handler is crunch the settings array so it is available with extensions as key under the variable swftools_actions. So we actually store this data twice,

    // Explode in to separate pieces
