[OzzModz] Country Flags by IP Address 2.2.1 Patch Level 3

Fixed the flags showing in forums that were selected to not show in.

Changed most of the template modifications from Simple replacement to Regular expression to hopefully avoid conflicts with third party styles.

Add - Download of database when MaxMind license key is entered or changed in add-on options

• Change - Return any errors generated prior to MaxMind database download during setup

• Remove - Check for BCMath from setup routine

• Add - Display country flag in spam cleaner
• Update - MaxMind database reader
• Remove - BCMath requirement

NOTE: While the requirement for BCMath has been removed, if your MaxMind database hasn't been updated in quite some time(as the cron task should be doing) you should keep BCMath or GMP installed so errors won't happen. MaxMind changed their database to eliminate using BCMath (or GMP) quite some time ago. But if you still have an old database file, it's still required.
