Edit Domain: enable setting the type for several variables at once

[ajdapretnar]

What's your use case?

Sometimes, one would like to convert several categorical variables to numeric (or vice-versa). This is not possible to do at the moment. One has to click every variables separately and set it.

What's your proposed solution?

Enable selecting several variables in Edit Domain and setting the type. I've checked and if the conversion cannot be done (i.e. transform text to numeric), the widget will output missing values for the erroneous variable. Which is quite smooth.

Are there any alternative solutions? /
