get_currentuserinfo deprecated

@gm_alex, I too would like to see the plugin be updated to be compatible with the most recent version of WordPress. I am getting the same Notice.

I just tried to fix it by changing Line 124 & 125 in user-access-manager.php from

get_currentuserinfo();
 $oCurUserData = get_userdata($oCurrentUser->ID);

to

//get_currentuserinfo();
$oCurUserData = wp_get_current_user();

Since the original $oCurUserData variable defines the ID of the current user we can replace it by wp_get_current_user()

This amendment has been submitted as a pull request at https://github.com/wp-plugins/user-access-manager/pull/2
