Wasted space in data directory

[buttim]

the data/js directory contains both bootstrap.bundle.min.js and bootstrap.bundle.js (192kB !).
I'm not bootstrap proficient but it seems to me that one of the two is sufficient.

Also minifying cameraslider.js would save 8kB.

Would it be possible to replace jQuery with Zepto? This would lead to another 80kB saving
