Attempt to fix evolved irregulars icons when used with decodence mods

Reuploaded and changed to higher version number to not show errors hopefully. I do allways forget to do something necessary

Thanks to Prowlercats bug report and Der Mentats advice I have finally fixed recruitment of all evolved units for all races

Tigran Wildcat was not recruitable in cities with Mercenary camp, fixed this (edit : unsuccessfully)

Reuploaded to work with 1.8

Added evolve ability to Feathered Serpent, it now evolves into Elder Feathered Serpent tier 4. Can be built directly in cities with Temple of Eternal Serpent Mystical upgrade and Archdruid skill Beast Mastery

By adding two new units I did incidentally removed Tigran Wildcats icon so had to repair that

- Dwarf Besieger attack increased from 11 to 13 physical (expert prospector has 13, was my mistake)
- Orc Breaker now needs Slaughter Pits mystical upgrade in city and player has to select Race Governance Military Upgrade 1 to build them directly

- Edited Dwarf Besieger Icon to look better
- Added Orc Breaker dualwielding unit evolving from Orc Greatsword. Ideal for breaking shielded armored formations of defenders. Buildable directly in cities with mercenary camp
- Added Frostling White Bow archer shooting frost arrows evolving from Frostling Harpoon Thrower. Buildable directly in cities with focus chamber and player needs to choose frostling Military Upgrade 1 (boosting hp for harpoon throwers)
