Unicode changes:
1. toggle UTF-8
1. login utf-8
Add utf8 as a toggle option and store in the nat_flags field in
nation structure. In the future, this should be a login option
rather than a country toggle once the login options are added.
Added a login options. The first option is utf-8 and it sets
the PF_UTF8 player's flags. Default is off.
Syntax
options utf-8 -- turns on the utf-8
options utf-8=1 -- turns on the utf-8
options utf-8=0 -- turns off the utf-8
options -- lists current options and their values

Notes for Client Implementors:
ASCII Mode
1. If you do not specify a login options, it the server will start the
session in ASCII mode.
2. This is close to the previous mode (<4.2.21) but there is more filtering
to remove non-ASCII characters and ASCII control characters.
3. If another client in UTF8 mode tries to send to this client then the
server will replace the non-ASCII characters with question marks.
4. The standout works the same as before where the 8th bit indicates that
the character should be highlighted.
UTF8 Mode
1. The login options must be specified before the play command is sent.
The syntax is 'options utf-8'.
2. The server will filter ASCII control characters but will pass any characters
with the 8 bit set.
3. For the standout mode, the server inserts an ASCII SO character at the
beginning of standout sequence and the server sends an ASCII SI character at
the end of the standout sequence.
