Updated to work with Osclass 3.2, cleaned a little

Hi, 

We want to include your theme in the "official" Osclass' market. I update it and cleaned a little bit.

* I added support url (forum) and a update uri (for market usage).
* I also upgrade the version of the plugin to 1.1.0.
* The author is still you.
* Added use of routes (calling the file directly will be soon removed from code)
* Moved admin.php to admin folder (more secure).
* Check if .htaccess file exists (avoid error)

We'll be happy if you agree and let us show your plugin in the market.

Regards
