Bug 1600099: Cleanup of the webservice admin page

This patch does a few things:

1. Renames "webservice_enabled" config to "webservice_provider_enabled",
to indicate that this config only controls Mahara's actions as
a webservice provider, *not* a webservice client.

2. Renames all the "webservice_<protocol>_enabled" configs to
"webservice_provider_<protocol>_enabled" to indicate that they only
control whether Mahara will provide webservices via that protocol,
and not whether Mahara will use that protocol as a client.

3. Renames "webservice_connections_enabled" config to
"webservice_requester_enabled", to clarify that this config
controls whether Mahara is allowed to request webservices
from external sources.

4. Updates language strings to make these changes clearer.

5. Rearranges and renames the form methods in
webservice/admin/index.php to make the flow of control more
obvious. Now the main form method is first, followed in order
by the methods that generate its subforms and each of their
submit handlers.
