Subject: [PATCH] Context is now accessible inside GetVersionCount()

globalized $context inside `GetVersionCount()` to eliminate `Notice:  Undefined variable: context in /var/www/html/ice/lib/settings-common.php on line 203`

Added check if file is readable for `.version-index`'s inside the loop within `GetVersionCount()`
