add an option to force to use UTF-8 for remote site

[tommywu]

This patch need the previous 2 patches I sent.

Add an option in site manager advanced option, allow
user to force to do the UTF-8 convert for remote site
(both ftp and sftp).

For the unicode build, I change the IPC for fz and
fzsftp, the local filename will convert to UTF-8 and
pass to IPC. (but the ansi build won't do this)

Under unicode build, I can access the file or directory
for both Chinese and Japan filename. The message show
in the status control in sftp mode will show some UTF-8
encode string. (because I convert it before the
showstatus() in sftp mode.
