Core/Account: Make account password change security variable and various 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 fulfills several new functions:
* Still prints GM Level.
* If account has permission, it displays the current email. This is not defaulted to any group.
* Security level is displayed. Also displays if user has RBAC perm if RBAC security mode is selected
.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.

Also fixes .learn all crafts.
Closes #10558
Core/Socket: Fix race condition in WorldSocket

ReactorRunnable::svc() checks the status of WorldSockets while WorldRunnable::run() updates them, causing a race condition.

Core/Spell: Fix farsight log error "Player requests non-existing seer"

Partially revert 167ca565d044915f01ead4b189754ab1c44cc981 which wrongly used TYPEMASK_UNIT to denote Creatures and Players, so when a Player sent farsight opcode with another Player as target HandleFarSightOpcode() couldn't find the right Unit filtering by typemask TYPEMASK_SEER.
