[max] Move all JavaScript URLs to the onclick event handler to prevent
breaking IE SSL in certain circumstances.
[cjh] Browser detection recognizes ie6.
[cjh] Added locale/se (Daniel Andersson <daniel@addelei.nu>).
[bjn] Ignore errors from PHPLIB session.inc posix_getpid (which isn't
supported by Windows 95/98/ME).
[cjh] Run $language through basename() before returning it in select_lang()
to avoid possible exploits, though a seperate bug in php needs to be
present to really exploit this.
[cjh] Reject From: addresses containing spaces, ';', or '&', and don't put
quotes around addresses (since sendmail doesn't strip them). If this
is too strict, we'll reconsider later.
