This removes the following functions that are not used anywhere:
- dt_add_rangedate_filter
- dt_overwrite_string_sorting_localeCompare
- replace_html
- replace_html_date
Test plan:
1. Search for calls to the above functions in the code. There should be
none.
2. Check that existing tables using DataTables are not broken.
