- It is useful to be able to replace some of the utility methods with
your own custom ones - for example a debounce rather than tha throttle
for filtering.
- This commit reorders the code a little to make that possible. No new
code is present at such - its really about reordering the current code
to make `$.fn.dataTable.util` the host for the original functions.
Backwards compatiblity is provided by assigning the util methods to
their old variables. With the next major update they should be removed
and the util methods used directly.
- Other util methods should be added at the same time, escapeHtml,
unique, etc.
- Fixes DataTables/DataTables #810
