Genome::Processes can run and be viewed

No schema changes this time.
Genome::Processes are now ready to be used (for example in VariantReporting).
I might extract this into a method or at least pull it out into a loop:

````
for(qw(UR_DUMP_DEBUG_MESSAGES UR_COMMAND_DUMP_DEBUG_MESSAGES UR_DUMP_STATUS_MESSAGES UR_COMMAND_DUMP_STATUS_MESSAGES)) {
  local $ENV{$_} = 1 unless exists $ENV{$_};
}
````
