msvcup: régebbi verziók és összes kiadás

Highlights
Newer Windows SDKs now work. sdk-10.0.26100.15 installed without headers such as winapifamily.h, so anything including windows.h failed to compile. These headers moved to new packages that msvcup now installs. Packages for older SDKs don't change.
More reliable downloads. The Visual Studio CDN sometimes ends a download early, which used to fail the whole install. msvcup now tries up to 3 times and logs a warning for each failed attempt.
Bug fixes
- Fixed a panic when piping large output in Git Bash, such as msvcup list-payloads | grep foo.
- Fixed >> redirection overwriting the start of the file instead of appending.
- Fixed download errors and logs that left out the URL.
- Requesting a package that doesn't exist now fails straight away and names the package. It used to write a lock file first and then report a lock file mismatch.
Other changes
- list-payloads now shows which msvcup package owns each payload, and lists every payload in the manifest.
- Added -h/--help.
- Moved package selection from code into src/recipes.txt, one rule per line. This keeps the payload-to-package mapping as data and prepares for making it configurable.

This release brings in our own MSI installer (http://github.com/marler8997/msi). The system msiexec.exe installer only works on windows, and also has intermittent issues such as failing if more than one instance is running on the system at at time. Our MSI installer fixes these limitations.
