Recognize Alts to avoid Mail stat inflation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Send mail from one character to another character on same account
2. Mail expenditure will tally the sent amount on sending character
3. Mail Revenue will tally the amount received on the recipient character.

This doesn't affect the overall profit/deficit totals, it does lead to a large 
amount of misrepresented numbers. If I send my alt 150,000g, the log will add 
this amount to both the expenditure and revenue tally and basically invalidates 
the count.

If there was a way to register/recognize alts and ignore money-mail between 
them, this would alleviate this issue and better represent the amount of gold 
coming and going from the account.
