Issue #218 - Do NOT allocate a 1 byte null String buffer. 

This is when setting a String config value through say tidyOptSetValue
using say tidyOptSetValue(tdoc,id,"").

If the length of the new string is zero then do not allocate a 1 byte
buffer, set it to 0, for the option. Any previous buffer has already been
released.

This means API functions like tidyOptSaveSink will not return erroneous
null String values!
