Quickfix to re-align direction of a Functional Exchange between different diagrams

[etraisnel2]

There is no synchronization on representations of Functional Exchange, between a Sequence Diagram and the others (the other way around actually)

For example,
on a SDFB
create 3 Functions F1, F2 , F3
create a FE between F1 and F2
display the FE and all functions on a Function Scenario
in the SDFB , modify the FE, by moving the target port to F3
the change isn't updated on the FE

a validation rule exist DWF_DS_19 that finds incoherence between the 2 diagrams
but there is no quickfix

Provide a QF to align the FE direction, so that source and target of the invoked operation are used for source and target of sequence messages
Provide a QF to do the other way around

Same check for all Scenarii in each phase, check for CE FE FC CM and Interactions
