Move modules to GitHub

We've moved four activities to github. (Turtle Art, Pippy, Chat and Log)
This patch remove the old repositories and uses the new repositories of these activities
Exit with error if run fails
Revert turtleart repository change

It's not fast forward.
Add gdb to the deps
Switch to github for sugar-base and sugar-toolkit
Pull turtleart from github
Simplify for sugar-web changes
Don't run checks for sugar-web
Run checks in sugar-runner
Remove web10Ln

It's pulled with volo anyway.
