drag and drop of columns and tables: multiple selections should be possible

[anthonydresser]

Is your feature request related to a problem? Please describe. With release Version 1.20.0 you've released the new feature of drag & drop from Tables or Columns into the editor for writing queries. A single table / column doesn't really solve a pain though; The real pain is when you've got to write (or drag & drop) every single table / column. For tables, it might be a bit less obvious but I can imagine the situation that you want to be able to put all tables you need beforehand so you can use them in getting things done style. For columns, its is fairly common that you want to specify many or all columns without using the wildcard as in `Select from Table`

Describe the solution or feature you'd like I want to be able to select multiple or all columns that I can drag & drop into the editor like I can in SSMS. If possible, there could also be a multi selection (which is not possible in SSMS either) of columns you want to use. Make sure that a comma is given into it. For Tables, just allow to pick tables and put into query window. To put the cherry on top of the cake: let the user give the option to pick either: columns are placed horizontally like Column1, Column2, ..., Column N or vertically like

Column1
, Column2
, ...
, Column N

and let decide if the comma is trailing or before column (as above)

Describe alternatives you've considered Alternative is to do this manually which may be a pain.
