Save user choices for columns in TSV

[birchamp]

When the user chooses which columns they want to see, this choice should be saved for the application so all TSV files open with those columns. gatewayEdit already does something similar.

DoD:

When the user adds or removes visible columns, changing TSV files or restarting the session, doesn't affect which columns are shown.

@elsylambert i have solved this issue and updated in develop

Test instructions

• Login into the app
• Select en_tn and book (eg: TIT)
• Click on the View column icon (Note only the rowHeader is clicked. In all books the rowheader will be default)
• click on the other columns checklist and change the book
• the selected columns remain the same for other books even if it doesn't effect after logout

Looks good in translationCore Create - v1.15.1 build 271-3c254b3. When user logs in for the first time, only RowHeader is checked by default. After the checkboxes are selected for the columns to show, the selections are remembered across the TSV repos(Common selections like Reference, Quote etc) and upon logging back in.
