Transition polish/fixes/todolist

[d-j-a-y]

• FIXME duplicated signals fix - see gtkadjustement (shared GtkAdjustment for the Shape value and not shared for Lenght ?) - af9e307

• FIXME transitioning from sample to stream |ESC| act strange :

  • From sample to stream, the transition shape and time come from stream properties (should be sample properties) - 3c51a72
  • From stream to sample, shape and length coming from .... ? - 3c51a72
  • From stream to sample, seems it's transitioning over himself?
  • From stream to sample (with multiple streams) ,sample problem with length (shape?) values

• FIXME when transition is activated the thumbnail in reloaded became not revelant

• FIXME reloaded / when minus on length == 1 ---> send 0 but updated in GUI to 25 - i suspect a bad value comming from server?

• FIXME reloaded / at startup, transition properties are not revelant. (shift-T the properties does'n update in GUI)

• FIXME doc!

• CHECKME stream <-> sample; stream appear without fx chain

• CHECKME high sample speed, transition problem ?

• FEATURE add key for activate by slot (speed / length)

• FEATURE sound transitioning (see Transitioning sound !  #258)
