Several optimization output overridable by theme

Issue Summary

Hi all,

First, thanks for this module, from what I've seen in the jungle of sliders, this one suits my needs. Except that I needed to override the output. I already did some hacking of the module for pasts project. Now I decided it would be better to give a patch to improve the module.

What does the patch?

• Auto rotate contents option is now working
• Glide animation duration option is working
• Direction option has been removed since I didn't find where this was implemented in the JS
• Removed unused (as far as I can tell) functions
• Respect Drupal naming conventions
• Removed unecessary permission
• Implemented administer content slider permission correctly
• Added hook_theme() and a theme_content_slider function so that we can override slider output at the theme level (not everyone wants a teaser, at least not me)
• Added t() calls where it was missing
• Removed t() calls where it was not necessary
• Moved inline JavaScript to Drupal scope with $(document).ready, so that we can put JS files at the bottom of page.tpl.php
• And other things I don't remember.

Not that using this patch, you will need to re-configure your Content slider settings.

I hope this helps, there is a lot to be done, mostly cleaning the JS file, which is not written the Drupal way and as there are many features that aren't implemented.
