Made Thankyoupage reloadable

Hi,

i'm not sure if you want to use that - maybe you would cherrypick (fine for me too!).

I made the thankyoupage reloadable which saves us a lot of time.

Also i fixed some paths in the metadata.

And - which maybe is wrong for you(?) i put all to the rootlevel. That helps a lot because you could use git directly in your project without copying to a second folder with that "copy_this" structure.
