Fix for asset pipeline (GPSHIRO-79) and Grails 2.4.4

[goeh]

When using the shiro-quick-start script the template for SecurityFilters.groovy does not work well with the asset pipeline plugin. All assets (images, css) are protected by shiro and you see broken images and no styles, unless you are logged in.

Adding a check for 'asset' controller fixes it.

You could arge that protecting assets are a feature that should be active by default but I think it causes more confusion than help for beginners. See https://jira.grails.org/browse/GPSHIRO-79

Found one more (duplicate) issue https://jira.grails.org/browse/GPSHIRO-82

Upgraded to Apache Shiro 1.2.3 and made sure the plugin works with Grails 2.4.4

Thanks for that, I'll try and manually merge those into the shiro2 plugin and make sure they are ported to the shiro 3 plugin.

I've been manually doing that myself :-)
