Interplay between regenerate and interactive

[aubertc]

I would expect the program to allow me to execute forward the "origin" of a process that already started its execution when I combine the --regenerate and --interactive flags.

However, this is not the case:

java -jar IRDC-*.jar --regenerate --interactive "((Tau{a}[k1].b|'b)|Tau{a}[k1].c[k4].0)"
------| Actionable Labels |------
[0] [k2]
[1] [k0]
[2] b
[3] 'b
[4] Tau{b}
[q] Quit program
------------
((Tau{a}[k0].b|'b)|Tau{a}[k0].c[k2].0)
Please input the index of the label you'd like to act on:

It seems that the --regenerate flag was completely ignored.
We can either

1. Embrace that behavior, but document it,
2. Try to make them play nicely together.

Also, the bug #76 is present here too.
