Menu system patches

[Serg Stoyan]

Hi,

The following patch correct some menu system related issues:

- main menu title was always set to process name. Now sets to
  process name only when menu is created via +new;

- observer and selector (_showOnActivateApp:) for
  NSApplicationWillBecomeActiveNotification notification added. Removed
  extra -update -display from NSApplication;

- reduce number of times getting geometry from user defaults for menus;

- while getting geometry from user defaults, use only position values
  not size (size is set by sizeToFit). This is avoids flickering of
  menu when actual size differs from defaults' size;

- right click on NSPopUpButton doesn't produce app menu inside
  NSPopUpButton's (reported by Stefan Urbanek in "NSPopupButton displays
  black menu titlebar" mail)
