Add two fields to the version model, for tracking release dates

This requires the following to be run on all developer installations:

alter table core_version add column "firstreldate" date NOT NULL default current_date;
alter table core_version add column "eoldate" date NOT NULL default current_date;
alter table core_version alter column "firstreldate" drop default;
alter table core_version alter column "eoldate" drop default;
