*reworked all travel army animations. as a result:
- there will not be any morphing/switching between travel animations anymore
- there will not be any graphical travel bug anymore for horse archer/camel archer armies while traveling
*improved some idle army graphics for foot only armies

*switched old siege graphic animations, which have been spread out too much and which have been similar to gathering graphic animations with an adjusted idle tent graphic animation => there will be 3 units with the siege animation now + siege weapon if available (like before) + tent, but without being spread out that much anymore
*adjusted some code
*included a bugfix for a minor vanilla graphical issue where blood effects would sometimes show up on a wrong place during battle with iberian christian tier 3 weapon (this bug was not caused by BG but i fixed it)
