Resolves
This PR builds towards resolving #84. Built-in Blockly block comments do not have IDs, because they're just represented as part of the block. Scratch's old implementation did have IDs, which get serialized and are tracked by the VM to maintain its internal state in response to block comment events.
This change makes block comment IDs the same as their parent block's ID with
_commentsuffix. In partnership with a forthcoming PR in -vm, this will allow for consistent comment IDs between -blocks and -vm, which in turn fixes the interop issues described in #84.Additionally, this PR fixes a bug that could cause the workspace and VM state to get out of sync due to events fired during block deserialization being suppressed.
