4.0.0-alpha001

• BREAKING #86 Changed the default rendering to use HttpClient, and abstracted the page rendering, so you can switch based on preferences / 🙏 enkelmedia
• Asynced all the things, or at least a big chunk / 🙏 enkelmedia
• Added tests / 🙏 enkelmedia
• BREAKING 6d6ab68 Terminology around indexing / rendering. The IndexingActiveKey is now RenderingActiveKey, helper method IsIndexingActive is now IsRenderingActive. The old things are obsoleted, so should still work. Planning to remove them if we ever get to 5.0.0
• BREAKING 6d6ab68 Detecting rendering/indexing is now based on a request header, instead of a key in HttpContext.Items.
• #82 Adds configurable markup for highlighting of search terms in result summaries. / 🙏 enkelmedia

dotnet add package Our.Umbraco.FullTextSearch --version 4.0.0-alpha001

I want to sort out #74 and #67 before releasing 4.0.0 - but do take it for a spin, and let me know if the change to using HttpClient is causing any problems :)
