Add GitHub issue templates and exclude .vscode-test.json from VSIX (#55)

* Initial plan

* Add GitHub issue templates and update .vscodeignore

Add issue templates (bug-report, feature-request, general-question)
modeled after vscode-fixcnchar. Disable blank issues via config.yml.
Add .vscode-test.json to .vscodeignore to exclude test config from
the published extension package.
