Deep Learning Texture Upscaler (merge)

[philyeahz]

Fix that branch (put executable in resources?) and merge it with the develop branch.

That stuff is way too big. (~500mb)
I'll implement it as an adhoc extension with an messagebox that asks you to download extra files to activate the deep learning feature in Tools menu. This feature will have an BETA tag, because it has problems with stuff like transparency. (at least for now)

Also:

• Implement a CUDA/CPU CLI Parameter
• Refreeze into executeable
• Investigate OpenCL usecase
• Publish python source code in separate repository (pre-freeze)

Workaround for transparency channel:

Input (argb)
rgb -> model
a -> grayscale -> model

Output (argb)
grayscale -> a
rgb + a -> output

Moved prototype stuff into separate Helper class and merged into dev branch.
