Transex3: NO_LOCALIZE_EXPORT

In the past, NO_LOCALIZE_EXPORT macro must be used to
skip uneeded parsing of src files which has no localizable content.
It is unsued by now and it is more effective to handle
this files on gmake level:
gb_SrsTarget_add_nonlocalizable_files
gb_SrsTarget_add_nonlocalizable_templates

Plus remove some empty src file.

Transex3: Simplify members for lists

No need for hashmaps (ExportListEntry) because only one
list is stored (en-US). One list member is enough instead of
one for all types.

Transex3: modify list localization/export part

Avoid using numbers to identify the list items because
using numbers can lead to mixed translations. Use the
corresponding string instead.
