Plugin Incompatible with PHP 7: Includes Fix

The plugin uses $variable->$variable_represting_string or $variable->$variable_represting_array['key'] in a few places.

The default interpretation of this syntax has changed in PHP 7.

You must now explicity wrap the variable in curly braces to get your expected functionality instead of letting php imply your meaning. Examples:

$variable->{$variable_represting_string}
$variable->{$variable_represting_array['key']}

These are backwards compatible changes for php 5.*
