HR fix for issue #235643

Hello,

I would like to ask for the review of the fix issue #235643 - 
Intellisense reports error on {{}} when object notation is used to pass 
paramter in earlier snippet

https://netbeans.org/bugzilla/show_bug.cgi?id=235643

The Angular expressions are parsed by our parser that doesn't support 
such expression as is mentioned in the issue. The fix adds the 
possibility to the parser.

There shouldn't be any risk.

Petr Hejl is reviewing the fix and Vlada Riha will verify it for QA.

The change set in the trunk is:

Thanks,
Petr
