r.to.vect: add option to not create attribute table if -v flag is used

Description
The -v flag of r.to.vect allows to use the pixel values of a CELL raster as category values of the created vector features. In that case and in certain circumstances it might not be necessary to create a database table for the output vector. It would thus be nice if r.to.vect had an option that would allow not to create an attribute table if the -v flag is used.

Try r57333.
The change is slightly different than requested: the creation of an attribute table can also be suppressed if the -v flag is not used, in which case a warning is printed out that raster values will be lost. Sometimes it might be useful to just have e.g. areas or lines with a unique category and the raster values are no longer needed.
Thanks ! I agree with your version of the change.
Won't have the time to test, though, as I'm leaving on vacation in a few hours...
