* BTCPay Extensions Part 2
This PR cleans up the extension system a bit in that:
* It renames the test extension to a more uniform name
* Allows yo uto have system extensions, which are extensions but bundled by default with the release (and cannot be removed)
* Adds a tool to help you generate an extension package from a csproj
* Refactors the UI extension points to a view component
* Moves some more interfaces to the Abstractions csproj
* Rename to plugins
.gitignore all the .DS_Store files in every folder and subfolder - improves UX
If you are using macOS, visual studio, visual code, rider, your system appends the .DS_Store file in your directories. It’s not a big issue, but often you need to exclude these files explicitly in your .gitignore file, to prevent any unnecessary files in your commit.
notice for btcpay Mac dev users..
This will never allow the .DS_Store file to sneak in your git.
But, if it's already there, you can write in your project terminal:
find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch
then commit and push the changes to remove the .DS_Store from your remote repo:
git commit -m "Remove .DS_Store from everywhere"
git push origin master
