Bug in algorithm, needs fix

The script doesn’t properly determine which file is the newest one. The IF statement on line 113 is incorrect.

Also the name “check_fileage” is confusing, it’s too similar to the natively provided “check_file_age” plugin.

My suggestion is:

1) Rename the script to “check_newestfileage”, and so a search/replace inside the plugin to change all instances of “check_fileage” to “check_newestfileage”.

2) Remove the “else” clause on the IF statement on Line 111, so change this:
