[Minor] Randomized anims for several behaviors

[Coronia]

Allow several Phobos anim logic to display one of the random anims in the list, instead of one fixed anim.

In rulesmd.ini:

[SOMESHIELDTYPE]                            ; ShieldType name
BreakAnim=                                  ; list of Animation
HitAnim=                                    ; list of Animation

[SOMEWARHEAD]                               ; WarheadType
Shield.BreakAnim=                           ; list of Animation
Shield.HitAnim=                             ; list of Animation

[SOMETECHNO]                                   ; TechnoType
PassengerDeletion.Anim=                        ; list of Animation
AutoDeath.VanishAnimation=                     ; list of Animation
Spawner.RecycleAnim=                           ; list of Animation
WarpOut=                ; list of Animation (played when Techno warping out), default to [General] WarpOut
WarpIn=                 ; list of Animation (played when Techno warping in), default to [General] WarpIn
WarpAway=               ; list of Animation (played when Techno chronowarped by chronosphere), default to [General] 

[SOMEANIM]                             ; AnimationType
WakeAnim=                              ; list of Animation
CreateUnit.SpawnAnim=                  ; list of Animation

[SOMETERRAINTYPE]  ; TerrainType
DestroyAnim=       ; list of Animation

Add a function to create random anim from std::vector<AnimTypeClass*> in AnimExt or something instead of copypasting the same thing across the place.

remove those duplicated 'Anims' tags, despite it might be a bit weird to not using plural for a list, it should remain backward compatibility and clearness. Also add random anim support for WakeAnim and Spawner.RecycleAnim

The definition of customizable WarpAway in Phobos seems to be wrong, as it should be the anim that the techno is erased by Temporal warheads rather than the anim used by Chronoshift, which should still use WarpIn and WarpOut. But here it hooks out Chronoshift's WarpOut anim and make it become the customize WarpAway.

Not sure if these tag definitions should be changed now that they might be made use by mods already, and I'm thinking if the WarpIn/Out of Chronoshift still deserves a customization. As of now I might keep them as they are while adding the random anim feature for them, but if there's an idea about how to sort out these tags then I could also try to implement them in this pull request
