Add support for extra visual studio and Nuget "manifests"

[pombredanne]

There are several files we could squeeze data from:

• packages.config https://docs.microsoft.com/en-us/nuget/reference/packages-config
• https://docs.microsoft.com/en-us/nuget/consume-packages/migrate-packages-config-to-package-reference
• https://docs.microsoft.com/en-us/visualstudio/msbuild/msbuild-properties
• https://docs.microsoft.com/en-us/visualstudio/msbuild/customize-your-build
• vbproj, csproj, fsproj VS "solutions" files

If this is available I would like to work on this issue.
Thank you.

Hey @s4-2, I contacted you on Twitter regarding this issue, could you take a look at that? 😄

Hey @pombredanne,
Sadhana told me that she is not currently working on this task, so I might take over.
Since I haven't developed anything for Scancode yet, it would be helpful to have an entry point. Could you give me some tips on where I need to start adding things and where I can look at existing code on this topic? I haven't found anything helpful in the documentation.

@mapelpapel sory for the late reply... but we also started the chat on Gitter... that's great.
@JonoYang do you think you could usher @mapelpapel there?

The base nuget handling is there: https://github.com/nexB/scancode-toolkit/blob/develop/src/packagedcode/nuget.py
and https://github.com/nexB/scancode-toolkit/blob/develop/tests/packagedcode/test_nuget.py
The first task would be to find a few example real files to use as test files.
