WebPositive Add option to start new session on startup

* Add settings file entry "start up policy", with two options:
   resume prior session, and start new session

 * Add dropdown to settings window to select option (defaulting
   to "resume prior session", which is the behaviour prior to
   this patch)

 * Add code to check setting on launch and open a new session,
   or reload the prior session as specified.

 * The "Start new session" option behaves in the same manner as
   opening a new window, following the user's already specified
   new window option

 * Related comment 2 of bug #14890
