Fix: Table could overscroll if `dt-init data` is used to populate the table
This is a fairly significant change to how DataTables operates for the
scrolling width calculations and primarily is due to a simplification
with the use of `clientWidth` to get the scrolling container width.
Rather than getting the offsetWidth and then removing the scrollbar
width if required the `clientWidth` will give us the value directly.
With the scrollbar width already accounted for the scrolling draw code
can be updated to not need to account for it itself.
Finally, when using the `data` property to add data to the table we need
to recalculate the column widths after the first draw, just like with
Ajax loaded data, otherwise the data added won't be taken into account
and we can get an error in the scrolling.
when body's position is changed (left: 375px) _fnBrowserDetect incorrecly calculates offsets. thus header is a bit misaligned. commit changes test object's position to fixed. in this case it's position will
be relative to the viewport not to the body.
When the table was being destroyed and the remove parameter was passed
in as `true` to remove the table from the DOM there was potential for
bound events to not be unbound from the table elements. This was caused
by the use of the `detach` jQuery method which will not remove events.
Furthermore, rows would not be added to the table before this method (or
`remove()`) was called. As such we need to reorder the code slightly -
attach the rows back into the DOM and then remove them (or detach if the
table is left in the DOM) - otherwise rows which were hidden by paging
would not have their events unbound.

finding and allowing this bug to be addressed!
Being able to get and keep a reference to each row is quite important.
You can't use the DataTables row index for this as it can potentially
change, but we can use IDs, based on a unique value for each row in the
data - `dt-init rowId`.
I've made the decision to not require escaping of data in the ID. This
means that selectors can be ID selectors with a cobontation of other
things (#div.class for example) as that really doesn't make much sense
in this contact - you only have rows that you can select from. Not
requiring escaping makes both the client and library code much easier.
This is documented.
The implemention is to store a reference to each row's data object based
on its id allowing for a trivial lookup. The object has its own index
in the `aoData` array, so there is no `indexOf` required. The only
downside is that the index must be updated when a row is deleted. This
is done with a trivial for loop.
* Issue was that an `error` event was being triggered before the
settings object had been configured. There is no option to trigger an
error event in this case.
* Fixes DataTables/DataTables #572
On line 605, column.sTitle is set to the TH's innerHTML.
On line 1816, column.sTitle is compared with cell.html().
If you have child elements with event handlers on them inside the TH, these are not the same in IE8 (see https://gist.github.com/simonbrent/933e552739477f4be3ab#file-test-html)
As a result, the check on 1816 fails, the contents of the cell is replaced, and the event handlers are removed.
Comparing instead with cell[0].innerHTML fixes this issue.
The main change here is to modify `_selector_run` to loop over the
extension functions (if there are any). This involves passing extra
information to the function (selector type so the correct extension can
be used, settings object and selector modifier to pass on to the
extension method).
The _selector_opts function has also been updated to give the ability to
use unknown properteries through a $.extend, rather than writing a three
property object.
