Provide feedback while waiting for the server to set the password

Due to its special nature the password is not stored in an attribute of
the model. Nevertheless, a "changed:password" (always with an empty
value) was triggered as soon as the password was submited. However, as
there is no password attribute that event is not taken into account
anywhere and the UI was not updated until the server response was
received (with further updates once the rooms are fetched again). To
provide feedback to the user that the password is being set now the
confirm button is replaced by a working icon while waiting for the
answer. In a similar way the input is also disabled to prevent further
requests while the previous one is ongoing.

Note that due to the aforementioned behaviour it is not really necessary
to wait for the server response to update the model with the new
password (as it will not be updated anyway), but it is done for
consistency with other requests.
