Version 1.1.1

* Updated debugging output of php_scripts/connection.php
* Added #!/usr/bin/php to the top of both cron/get_feed.php and cron/clear_read.php so that they will run as cron jobs.
* Corrected file paths of cron/get_feed.php and cron/clear_read.php
* Added a chevron-left icon to be displayed for backward navigation when displaying an article in the mobile version.
* Added code to php_scripts/update_feed.php to store the titles from feed as HTML safe characters. php_scripts/load_article.php and php_scripts/load_feed.php convert HTML safe characters back to HTML for the feed titles.
