[mousetweaks] Add property for target-time

[Gerd Kohlberger <gerdk src gnome org>]

commit 1fac4c22591d4fff896d6e50deff9c6a7c7b0083
Author: Gerd Kohlberger <gerdk src gnome org>

    Add property for target-time
    
    We can use this to bind the property to DConf values, once we
    migrate to GSettings.
