t2i function

Text to HTML-Input-value conversion

function t2i ($str);

Parameters:

str

Remarks:

Change " into " (and other HTML entity replacements)
Good for use with <input value="...">

This also removes any line breaks which must not occur in HTML tag attributes.
removing line breaks especially fixes an XML error for the ABBC parser that would
replace \n by <br/> in the end, leading to a <br/> tag inside the attribute which
is invalid XML.
