Creation of /assets branch set

[aakatz3]

Is your feature request related to a problem? Please describe.
Presently, external asset dependencies, such as mojangles_width_data.json and textures.json are created in external repos, and are hosted externally. They are also downloaded into the project through multiple methods.

Describe the solution you'd like
The creation of a set of assets/ branches, with runners from the separate repos, which create and publish the assets directly to StickyAPI's gh-pages, under an assets or resources subfolder.

I'd also like the creation of a file download task, with associated clean tasks, in the build.gradle which will be used to get any specific needed resources.
