prepare for documentation update

README -> OLD_README
update mysql-querier to handle an options object

instead of tacking on more arguments to the method or
creating a new method altogether, an options object can now be
passed into createReadStream();

this is due to the large amount of options necessary
for the project and the variable nature of where they are
necessary or not necessary.

additionally, the createReadStreamWhere has been removed
this functionality is replaced by the "where" option

users of the method will have to replace any createReadStream
and createReadStreamWhere instances with one that uses an options object
unless they were only passing a table argument; in which case,
they don't need to change anything
