Remove all facadminVo artifacts from Perun
CORE, GUI: changed Perun's URL structure

- Use new URLs in GUI and CORE.
- Devel config files: perun-rpc-lib.properties and
  perun-registrar-lib.properties are already updated.

New URL scheme for devel:

/[authz]/rpc[-personal_login]/
/gui[-personal_login]/

New URL scheme for production:

/[authz]/rpc/
/[authz]/gui/
/[authz]/registrar/
/[authz]/pwd-reset/ (Fed for now leads forceFedAuth URL,
                     others leads to normal RPC)
/perun-identity-consolidator-[authz]/ (back to old scheme, will be implemented later)
