* Added a parameter called "Size" to the "RadzenGravatar" component. This will allow for users to adjust the size of the gravatar image coming in, so that they are not stuck with just a 32px image.

* Corrected the default value from 32 to 36, and remove the width variable in favor of the parametised Size variable. (As per suggestion from akorchev - thanks)

* Corrected a typo where the "value" attribute was inside the summary, it is now outside, where it should be.
