2sxc 20.00.05 MoT - fixes and caching

2sxc v20 cleans up a lot of history, so it has breaking changes.
These mainly affect old code, so they should only affect DNN installations which have old code on it, or used old samples to develop Razor.

Read about it in the blog: https://go.2sxc.org/v20

See also the docs with all the changes and breaking changes

v20.00.05 Has very cool enhancements which we'll communicate later ;) + some bug fixes
