Remove cpp script for seaforium depth charge ((Bury those cockroaches)).
DB/SAI: Jenny (Load'er UP)

Ok so found I needed to rescript this to as had not noticed there was already a script on Fezzix Geartwist for this quest, this sai has got same flaws as cpp version had, when npc gets attacked and evades looses crates aura (another example of the thing with auras getting removed at evade causing problems),
Remove CPP script for Jenny/Jezzix Geartwist
CI/Travis: Yet another attempt at reducing the number of killed builds
Core/Net: Fix GCC build
Scripts/The Barrens: Make BIG WILL attackable in quest id  1719 (the affray)
