[Soc-2017-dev] Daily Report - Jul 27 - Package Manager

[Ellwood Zwovic]

Today I talked with some users testing the package manager in the 
renderfarm (blender.stackexchange chat). We discovered some bugs and UX 
issues:

* Install dies inelegantly if it runs out of hard drive space (this was 
a known TODO, but amazingly, already someone actually happened to fill 
their harddrive while installing a package)
* Repository should be displayed with other package metadata, otherwise 
there isn't really a way to know where it comes from. (this is done 
already in case of multiple versions)
* Error messages could be clearer

I started addressing these, and I got the demonstration video uploaded 
(I linked it earlier, but here it is again: 
https://www.youtube.com/watch?v=b_iBVNmeBdM). I also updated the readme, 
as the instructions weren't totally clear (and some other parts were out 
of date).

Tomorrow: bug fixing and stabilizing, more testing (possibly on other 
platforms), and (again), make uninstalling easily reversible.
