AppVeyor: Cleanup, minor changes

Ignore commits to README.md, and /.github;
 This is future proofing for GitHub Actions, new issue template, etc.
Capitalize Ubuntu.
Change configuration to Release Optimized.
Proper multi-command formatting.
Use env matrix instead of shell to seperate steps for Windows and Linux.
Add LICENSE to artifacts.
Remove artifact type since it's unneeded.
Windows:
 Use AppVeyor's build thing.
 Remove build verbosity since normal is the default.
 Remove build\bin crap from the zip.
Linux:
 Make apt-get into one step.
 Speed up build by using -j.
 cd into APPVEYOR_BUILD_FOLDER to avoid problems.
