Suggest typo correction for unmatched template variables

[warpech]

As an enhancement of #11, it should be possible to suggest fixes for common typos in cased of missed TemplateBinding.

Typical typos:

• name -> Name
• Nmae -> Name
• Name -> Name$

This is point 6 and 9 from https://github.com/Starcounter/Starcounter/issues/2468

@alshakero I am not sure if it is possible to implement it in Starcounter DevTools, but perhaps this can be done in JSONPatcherProxy?

In case JS tries to read an undefined property from the data model, check if it is one of the common typos and print an error like:

The script tried to read the property Name from the data model , but it is undefined. Did you mean: Name$? If you want to use variables outside of the data model, please follow the Palindrom instructions on ignoring the local data changes: https://palindrom.github.io/docs/03-_Filtering%20Patches/

@tomalec, @alshakero WDYT?

I think if we cannot implement/monkeypatch it in DevTools we shouldn't do that, as it affects runtime performance and a clerk at the POS at the ship does not care about console errors, just want this app to run as fast as possible.

I totally agree with that, we should only do that in DevTools extension.

[alshakero]

Me too. My prospective opinion is that it's easily doable in SDA.
