Thomas Weber 2d29cdc63a Quit VM when execute test times out 
A future test project will be designed such that failing to
quit the VM after timing out would severely inhibit the
performance of the other tests.

Muffin 6ce931b60a Add test for behavior of self-restarting scripts 
The behavior is non-trivial as it will keep running the old thread
unti it yields.

I briefly tested putting `thread.status = 4` at the start of _restartThread
and all the old execution tests still passed, so let's just add a bit more
coverage. This was nearly regressed by f548d1b33c.

Muffin f548d1b33c Fix stopping a thread from inside of its blocks 
Works in command or reporter after yielding or not.
These snippets are covered by the tests:

sequencer.retireThread(thread);

Muffin 0593628e24 Fix rejected promise behavior in interpreter and compiler 
Before this command:
- Interpreter would popStack() and continue. Inside a loop this was like JS continue, outside it was like return
- Compiler would return literal undefined and keep going.

After this commit:
Both return the error as a string and then continue as normal.
This has several benefits:
- Users can actually see the error messages
- Logical execution flow
- Consistent behavior
- Blocks aren't even supposed to return rejected promises anyways
- No vanilla blocks return rejected promises so no compatibility concerns

JeremyGamer13andMuffin 31c9eba1aa Add platform info (#205) 
- Platform info is now stored in project.json.
- Available to extensions on vm.runtime.platform.
- When loading a project with a different platform, emit an event and wait for callbacks before continuing.

GarboMuffin 20f25f252c interpreter: Do not re-evaluate procedure arguments after stop this script or return (#202) 
"stop this script" and "return" would previously cause all the procedure
arguments to be re-evaluated and then discarded. In vanilla Scratch the
worst case is a performance penalty, but with our custom reporters it
can cause infinite loops.

Muffin 9657efb1d4 Shorten Base64Util test cases

tpsntandMuffin 845c374f72 Fix WeDo2.send sends empty message (#192) 
* Fix WeDo2.send sends empty message

WeDo2.send invokes Base64Util.uint8ArrayToBase64(message). However message.arrayLength === undefined. This causes Base64Util.uint8ArrayToBase64 always returning empty string ''.

* Move the fix to base64-util instead
