Create centralized column alias feature for all columns in the data set

[geoerika]

Issue:

• the current implementation of column aliases is a bit sluggish & slow to use when the browser is very busy, as it updates the data in the widgets right away

Solution:

• build a separate Column Alias Configuration feature in the left panel that gives the user the opportunity to change the column alias for all columns at once, and only updates by pressing a Submit button
