This change renames block name from [arex/ws/emies]
to [arex/ws/jobs]
all over the code and configuration to make master build operational.
It DOES NOT change the internal structures that in some cases still use emies-based naming, like:
$config->{arex}{ws}{emies}
or
if (cf.SectionNum() == emies_secnum)
Internal structure naming only affects pettiness of corresponding internal names, but not the functionality itself.
People responsible for particular components can improve prettiness later if needed.
