Core: Fix a bug in BigNumber::SetBinary
Fix BigNumber::AsByteArray function by returning Auto_Ptr.

Remove mutex from BigNumber class - it didn't do what it was advertised to do - consider using the "locked" array outside of the function in which it was "locked".
Fix crashed caused by using openssl from multiple threads simultanously.

Note that this doesn't make BigNumber class threadsafe - it never was that way.
Update rename for openssl changes
Core: Fix warnings. Make callback symbols local.
Core/Account: Make account password change security variable and various email changes

Settings within worldserver.conf:

Three settings for secruity level:
0 - None - No change to current system
1 - Email - Always requires the email entered on registration for confirming.
2 - RBAC - Groups applied with the RBAC role always require the email entered on registration for confirming.

RBAC default to every group. Changed some logs to make it more clear what is going on at all.

Emails may now no longer exceed 64 chars. Current email is used as regmail.

On account creation, two emails are saved. Registration email and normal email. Normal email is relevant afterwards. Registration email can be changed by console ONLY.

Includes new commands and changes to existing ones:
.account now also displays email if you have the rbac perm. Not defaulted to any group.
.account email allows user to change email with sufficient confirmation
.account set sec email allows higher sec with higher sec than account to change the normal email. Registrationemail remains untouched here.
.account set sec regmail allows console to change registration email.
.pinfo now displays the registration and normal mail.
