Updating readme, knownissues link and clientside blazor

[patrickhacens]

upading read me with info from issue #93

[SeppPenner]

Looks good for me. Some small changes from my side:

• I would close all sentences with a dot
• Describe what PROBLEMATIC_COMPONENT stands for and provide an example, e.g. "PROBLEMATIC_COMPONENT here means a specific chart component like ChartJsLineChart"
• "For more information, check out our known issues page" (With the link of course as you already have it)

Before you change something here, please wait for @Joelius300 remarks, too. He might have some more ideas.

And thank you for the pull request. I wanted to do that but didn't have the time yet :D

I approve the comments of @SeppPenner. I can only emphasize that the example for the ReferenceConverter stuff has to be very clear.

@Joelius300 I integrated this into #98 (Because both are changes in the readme) to get this done.

Since there were a few changes for the readme that could be done together, this pull request is now unnecessary since your work has been reused in #98 :)
