Memory: Properly initialize and free new module languages.

Memory: Properly free strings in module config directive lookups.

Memory: Do not leak module version and author in rare situations.

Memory: Memory leak when deleting a module callback.

Memory: Memory leaks with module messages.

Memory: Memory leaks with module commands.

Memory: Memory leaks with module event handlers.

Memory: Memory leaks with module event hooks.

Memory: Every module config entry of type string is leaked on config reload.

Memory: Leak services root list, ulines list, host setters list, modules autoload list, modules delayed autoload list, hostserv/memoserv/helpserv/botserv/operserv/chanserv/nickserv core modules lists on config reload.

Memory: Leaks with channel bans/invites/exceptions.

Memory: Leak when updating already existing ignore.

Memory: Invalid pointer read in slists.

Memory: Leak when using /cs appendtopic.

Memory: Leak on (currently impossible) config reload.

Memory: Syscall param write(buf) points to uninitialised byte(s) in save_ns_dbase().

Memory: Leak if PreNickServDB is set and NSEmailReg is not.

Removing a command no longer calls free() on help_param*, reversed previous changes
Changes to CSMaxReg, MSMaxMemos and NewsCount are now properly reflected in help notices after config reload
Small adjustments

Fixed copy&paste mistake
