Validate handlebars

[adrinr]

Description

Validating handlebars on the binding panel. For now, we will be only validating the following:

1. Fields parameters (TODO in a further PR)
2. Helpers parameters
3. If helper required a body, validate it is set
4. Within a body of a helper, we only validate other helpers (as we don't know what keywords can the helper use, such as index, this...)

Screenshots

No errors

Helper with missing parameters

Helper with too many parameters

Helper with missing required body

Wrong helper within a helper

Invalid HBS code

Checked this out and had a look at it - ran into a few issues - it seems handlebars statements with spaces in them are not validated correctly, for example the Query Params based on the URL:

Also components which have spaces in their name suffer from this same problem, e.g. table - table 1 (auto-generated screens can appear like this).

This is caused by the difference between runtime vs readable values. This required a much bigger job, as we will need to handle whitespaces properly. I will be doing this separately, as it might grow quite a lot. We will need to handle also other type of expressions, such as arrays.
Meanwhile, I updated this branch to only validate hbs helpers, as this will already add value.

Works well in my testing 👍 Nice job @adrinr.
