webadmin,userportal: Progress indicator during login

This patch makes sure that a progress indicator, represented
as the 'wait' mouse cursor, is shown during the entire login
process.

>From UiCommon/GWTP point of view, the login process consists
of following steps:

 0. Default place of login section (#login) gets revealed

1a. If the user is already logged-in on the backend:
    * UiCommon LoginModel is instructed to sign the user
      in automatically by calling its AutoLogin method
    * AutoLogin method takes care of populating appropriate
      UI fields (UserName, Domain) and fires LoggedInEvent

1b. If the user is NOT already logged-in on the backend:
    * User fills the login form and hits Enter/Login
    * UiCommon LoginModel is instructed to initiate the login
      operation (authentication) by calling its Login method
    * If successful, Login method fires LoggedInEvent

 2. WebAdmin/UserPortal ApplicationInit.onLogin method gets
    called in response to LoginModel's LoggedInEvent:
    * Both WebAdmin and UserPortal do some early init logic
      and then call BaseApplicationInit.performLogin method
    * BaseApplicationInit.performLogin represents actions
      taken by UI after successful user authentication

 3. Default place of main section (#vms) gets revealed

Instead of showing/hiding progress indicator for each of the
steps outlined above (e.g. using LoginModel "Progress" for
the authentication operation in step 1b), progress indicator
is shown once, when the actual login process starts (1a/1b),
and is hidden after reaching main section (3).

LockInteractionManager is the class responsible for handling
progress indicator. For now, it only reacts to "GWTP place
transition finished" events, in order to hide the progress
indicator after GWTP place transition (e.g. #login -> #vms).
In future, it can react to "GWTP place transition started"
events as well.

For now, there is only one kind of progress indicator:
'wait' mouse cursor (applicable to login section). In future,
there might be another kind of progress indicator applicable
for main section.
