(I appied the 0006234 patch to 1.0.0rc)

0006234 adresses only newly created filters. For the old filters I had to add a patch similiar to the one in 0006291, just that '( $t_filter['view_state'] != "any" )' had to be added, because some old filter used this.

In my opinion it would be important to add a "stored filter update procedure" in the upgrading-process (which maps "view_state" "any","0"... to "[any]", I don´t know what other issues need to be fixed here).

Otherwise Mantis would either be incompatible with previously stored filters or had to add compatibility patches in the current filter code, which does decrease the consistency of the rather tricky filter code.
