PR Validation

[daveaglick]

With the update to the latest Statiq, we can now easily write analyzers and validators to check PRs. This should give me a lot more confidence to merge quickly. Some initial thoughts on specific validations:

• Make sure all files under the data folder are .yml files and follow other naming conventions (all lower case).
• Check URLs for projects to make sure they exist
• Check URLs for blogs and broadcast feeds and websites to be sure they exist
• Check other URLs are well-formed and exist (resource website, chat and docs for projects, etc.)
• Make sure NuGet packages are just the package name and not a URL
• Check Twitter handles of projects
• Check for duplicates in all categories (based on title? maybe source code for projects?)
• Image links are all full URLs and use https
• Projects use an approved language
