Unity 7.2.1 "14.04 SRU 1"

  [ Brandon Schaefer ]
  * Set the max width, so our static text wraps. So we don't end up
    rendering text out of the view area. (LP: #1312749)

  [ Jnkyu Yi ]
  * fixed range of blacklisted Unicode characters (lp: #1251193)

  [ Marco Trevisan (Treviño) ]
  * UnityScreen: toggle activation of all the unity compiz actions when
    locking the screen Also, make sure that the lockscreen views are
    treated as "always-on-front" windows by nux (and this applies to
    both visibility and events).
  * PanelService: emit an invalid EntryActivated signal if the menu
    hasn't actually been shown In addition, if the menu is not visible
    after the first popup call, try to show a menu without keyboard
    focus. This will make possible to see menus also when there's a key-
    grab (although they will be without keyboard support). Finally,
    reset the menu state, if that failed.
  * UnityScreen: always paint the lockscreen above, just add menu and
    onboard as exceptions Some code cleanup, factorizing similar code.
    (LP: #1313280)
  * PluginAdapter: make sure we don't try to call an invalid
    initiate/terminate callback function (LP: #1221673)
  * DebugDBusInterface: match properties if they are in the AP array
    form [<type>, <value>] (LP: #1307748)

  [ Stephen M. Webb ]
  * lockscreen/LockScreenAccelerators.h: added required header for
    std:vector definition (fixes FTBFS in Ubuntu)
  * disabled precompiled headers on arm64 Ubuntu package builds
    (lp: #1317276)
  * bump upstream release to 7.2.1

  [ William Hua ]
  * added proper support for modifier-only shortcuts on the lock screen
    (lp: #1291461)
