Remove lock start and lock end functions

[romicolman]

Problem description

When clicking on the column options (datagrid), the user will see these categories:

The lock start and lock end functions do not add any value to the user. Same with the Group and Ungroup functions. In this latter case, they are always inactive. I tried different things to get them enabled and they don't seem to work.

Steps to reproduce it

• The user opens the ODE
• Goes to ADD--FILE and then selects a tabular file.
• Once data is previewed, the user clicks on the options next to the name of a column.

Suggested solution

• Remove the lock start and lock end + Group and Ungroup functions.
