added demos, user badge, blurred email and default picture(penguins of madagascar)

overworked login, register, profile, community , game_detail , dashboard and edit game

So today I added Demos you can install.
I just copied the code of the game upload.

I also added a user badge so you can see who is a dev and who is a user.

Now youn will also not see your whole email but reade just the first three letters. (That took way too long to do)

And I also overworked all of these pages so they have a look that better fits the entire store.
