First step towards delta based history

Browse Source 
Introducing independent change detection for appState and elements

Generalizing object change, cleanup, refactoring, comments, solving typing issues

Shaping increment, change, delta hierarchy

Structural clone of elements

Introducing store and incremental API

Disabling buttons for canvas actions, smaller store and changes improvements

Update history entry based on latest changes, iterate through the stack for visible changes to limit empty commands

Solving concurrency issues, solving (partly) linear element issues,  introducing commitToStore breaking change

Fixing existing tests, updating snapshots

Trying to be smarter on the appstate change detection

Extending collab test, refactoring action / updateScene params, bugfixes

Resetting snapshots

Resetting snapshots

UI / API tests for history - WIP

Changing actions related to the observed appstate to at least update the store snapshot - WIP

Adding skipping of snapshot update flag for most no-breaking changes compatible solution

Ignoring uncomitted elements from local async actions, updating store directly in updateScene

Bound element issues - WIP

| `skipSnapshotUpdate` | `boolean` | Implies whether the `store` should skip update of its snapshot, which is necessary for correct diff calculation. Relevant only when `elements` or `appState` are passed in. When `true`, `commitToStore` value will be ignored. Defaults to `false`. |
