Support for Spam Filtering Using Akismet.

[thousandtyone]

PR Contains Fix as described in #599. Entire end to end flow has been tested and works. Here are the high level changes that are done:

1. Migrated the Akismet projects using DotNet Upgrade Assistant. More information about this tool is at: https://docs.microsoft.com/en-us/dotnet/core/porting/upgrade-assistant-overview. The migration was smooth without any errors and the entire project was moved over to .NET Core 6.0.
2. Wrote code to integrate with the project. (Very similar to the old DasBlog project). Note that some simple changes were done to fit in the correct structure. E.g. Akismet with spam moderation works fine and integrates in correct comment moderation framework. Without comment moderation, any spam detected by Akismet is stopped from getting posted using validations.
3. Config file already had the right XML nodes present but the Models in CS files had some of those attributes commented to uncommented those.

The end to end flows work. More documentation with screenshot of how this works appended with the issue. Happy to make any other changes that you feel might be required.

The Same command however works locally for me:

Not sure if I did something wrong or it's an issue with the pipeline in general. The whole flow is working perfectly on my machine and even seems to be passing build and test cases in the pipeline. Not sure why publish is failing. Right now I tried the same set of commands the pipeline is firing on my local machine and it all seems to work. If there is something that needs to be fixed at my end please do let me know and I'll be happy to fix. Not sure why the publish is unable to find the akismet dll on the pipeline box. I am leaving the PR open. It'll be really nice if you can review it once and please do let me know if I am doing something wrong or it's some issue that needs to be fixed on the pipeline. If I need to fix it, I'll do that right away.

@thousandtyone Thx for the PR. Sorry I took so long to respond. I will take a look at this in the next day or so.

@thousandtyone Again thanks for your patience. I have been told I need to fix an issue with the build (Framework dependency is broken).

So my plan at first was to attempt to resolve this issue at the same time, but in all honesty I am feeling less comfortable about making Akismet part of the dasblog project directly. I have spent a lot of time trying to narrow the focus to the essential and necessary and just consume Nuget packages. Here are my thoughts:

1. Create a new github repo for Akismet
2. Develop the pipeline to create a Nuget package
3. Consume the package in dasblog

I am not sure how you feel about doing this work, I also do not want to assume that I can just take your Akismet project and just make a Nuget package under my Github name (I am really happy to do this but again, how do you feel?). Please let me know which way you would prefer to go.

Again, thanks for your contributions!

[thousandtyone]

@poppastring Really sorry about the rather late response on this one. I am absolutely fine with taking any direction you would want to take. Please feel free to take my work and make a nuget package under your github name. No worries! As long as dasblog gets akismet support we all benefit from it! :)

Also if there is any way in which I can further contribute or help please feel free to let me know.
