Please refer to #2694 and #2670 for motivation and reasoning for
this change.
I've tried to follow best practice in inserting the copyright
headers. In other open source projects, not all files carry
the notice. For example documentation doesn't. I've followed
similar ground rules.
I did not change the php because there is a separate LICENSE
file there by Pixel Federation. We'll first need to notify
them our intent before changing anything there.
As for the presubmit check, it's going to be non-trivial
because of the number of exceptions, like file types,
directories and generated code. So, it will have to be
a separate project.
After node is freshly installed, it is not part of PATH. By sourcing
dev.env, we fix this.
I've also changed the file of the temporary, downloaded file to include ".tar".
The test requires many dependencies which prolong the current test duration by up to 10 minutes on Travis.
Once we figured out how to cache the dependencies both on Travis and our local machines, we can re-enable the test.
Instead of commenting the code for installing the dependencies, I've moved it to bootstrap_web.sh for now.
