Migrate WTF script

Intoduction
The following script allows you to change the realm / character names within your WTF. It is used in the following situations:
 * Copying your WTF to the test realm installation
 * Moving your characters from one realm to another
 * Forced to rename your character

The script was developed and tested on a Mac, however it can be run on Linux as-is and on Windows via cygwin.

Usage
The script can be stored and run from anywhere.

migrateWTF.sh -a [-s &lt;source dir>] [-d ] -f -t {-o -n }

-o and -n must be specified in pairs; zero or many -o -n pairs may be specified.

Additional Information
To migrate from one realm to another within the same WoW installation i.e. you have moved realms, you should specify the same -s and -d. The old configuration will be backed up to: World of Warcraft/WTF.beforemigration

Limitations
Only one account may be migrated.

Only one realm may be migrated; you cannot have multiple from or to realms.

Migration from your realm to the test realm without renaming any characters
./migrateWTF.sh -a NEMES11 -s "/Applications/World of Warcraft" -d "/Applications/World of Warcraft/WoWTest" -f "Dath'Remar" -t "Test Server (US PVE)"

Migration from one realm to another, renaming two toons
./migrateWTF.sh -a NEMES11 -s "/Applications/World of Warcraft" -d "/Applications/World of Warcraft" -f "Thunderhead" -t "Privybush" -o Nemes -n Nemesy -o Rhad -n Dhar
