* src/modest-tny-account.[ch]:
        * New method modest_tny_folder_store_is_remote, coming from a
          specific maemo modest_platform method. As this does not have
          any platform specific code, we moved it to a common place.
        * Use hildon calls only in maemo.
* src/modest-platform.h:
        * Removed method modest_platform_is_network_folderstore,
          replaced by modest_tny_folder_store_is_remote.

          its initialisation.

        * Now show_help method returns void.
        * Added new methods connect_and_perform, and
          connect_and_perform_if_network_account. These methods act
          as it's always connected.
