Dumpvariables rewrite new syntax plus search

[pmario]

This PR is a draft atm. It's "Work In Progress". These extensions where inspired by @AnthonyMuscio at Talk

• It improves the dumpvariables macro and uses v5.3.x syntax
• It adds a completely new search-variables macro
• It is proposed to add the new search-variables feature to the $:/AdvancedSearch

The search-variables macro allows us to filter the list with a search text-input

For testing the PR adds a new tab to the $:/AdvancedSeach dialogue

The list can be extended, which opens a second search input, that shows, where the macro text is used and/or where it is defined. While working with the macro it turned out to be a very useful feature.

@Jermolene @saqimtiaz ... What do you think?

I'll start a new thread at Talk, to get some feedback there too, once Vercel built a preview.

The second input allows us to add more words to the filter string, to shorten the list

@pmario I would highly recommend having separate PRs for new features, and for the syntax rewrite of existing macros. Especially for the latter that would make it much easier to review and merge them.

[pmario]

Yes, I can do that, since it's only 11 lines of code. Then this PR will completely rewrite it.
