This is our primary input filter.
The high bit hack only involved some old IE browser, forget which (IE5/Mac?) that had an XSS attack vector due to stripping the high-bit on an 8-bit character after cleansing, and angle chars with the high bit set could get through as markup.
This is now disabled because it was interfering with some legitimate unicode sequences and hopefully there aren't a lot of those browsers left.
Use this on any text input where angle chars are not valid or permitted They will be replaced with safer brackets. This may be filtered further if these are not allowed either.

It is expected that this function will be called using HTML text. We will escape text between HTML pre and code blocks from being processed.
At a higher level, the bbcode [nosmile] tag can be used to prevent this function from being executed by the prepare_text() routine when preparing bbcode source for HTML display

| zidify_callback | ( | $match | ) |
zidify_callback() and zidify_links() work together to turn any HTML a tags with class="zrl" into zid links These will typically be generated by a bbcode '[zrl]' tag. This is done inside prepare_text() rather than bbcode() because the latter is used for general purpose conversions and the former is used only when preparing text for immediate display.
Issues: Currently the order of HTML parameters in the text is somewhat rigid and inflexible. We assume it looks like and will not work if zrl and href appear in a different order.
