CORE-4167 Fix for Sessions loading at start-up.

Sessions were loading even when users had Sessions disabled.
The user's Sessions-enabled flag is fetched from the user's Preferences.
Moved the getUserSession call in DEPresenter from the initializeUserInfoAttributes method into the loadPreferences method.
Moved the loadPreferences method to a more logical part of the file.
CORE-2925 Refactored Intro dialog box in DEPresenter.

Renamed parseWorkspaceId to parseWorkspaceInfo, since it also parses the "isNewUser" flag for the UserInfo object.
Refactored the "Welcome" confirmation box into an initIntro method.
Called this method from parseWorkspaceInfo, since this is where the "isNewUser" flag is parsed.
CORE-2925 Minor refactor in DEPresenter#parseWorkspaceInfo.

Removed extraneous JSONObject parsing.
The UserInfo#init method just needs the JSON string.
CORE-4167 Refactored Periodic Session Save calls.

Renamed DEPresenter#initPeriodicSessionSave to doPeriodicSessionSave and added it to the DEView#Presenter interface.
Removed this method call from doWorkspaceDisplay, which is called by a successful initializeUserInfoAttributes service call.
Instead, doPeriodicSessionSave will be called from the UserSessionProgressMessageBox#GetUserSessionCallback, to ensure session saving does not trigger before a session restore is attempted, but also after User Preferences have been loaded.

CORE-4541 Fix for idrop-lite applet in Windows.

The bug from 1.6 where the applet always stays on top of everything else in the DE is still an issue on Windows machines.
Re-added the logic to minimize the idrop-lite window whenever it loses focus, or when the user attempts to close this window and the confirmation prompt needs to display.
