[PATCH v2] Conflict option labels

Hi,

here's the second version of the conflict option label patch.
Changes:

- reworded some labels
- now using apr_array to pass around options
- renamed and simplified svn_client_resolver_option_label

The functionality has been lightly tested by creating conflict
scenarios.
