Version 1.1

* Updated css/bootstrap_custom.css with screen width conditions
* Change index.html to index.php; all other files updated accordingly.
* Updated php_scripts/get_feed_menu.php, php_scripts/load_feed.php and php_scripts/load_article.php to display appropriate HTML code for the mobile version of the site.
* Added code to php_scripts/update_feed.php to remove javascript from feeds before insert into the DB.

* Created js/mobile.js for mobile adapted versions of the functions in js/main_screen.js and js/menu_col.js
* Reduced time between reloads of loadMenuCol() in js/menu_col.js from 15 minutes to 10 seconds.
