Added config options for datepicker and a max length for selection-box option labels

[GoogleCodeExporter]

I don't see a spot for contributions to the project, so I'm doing it here.

What steps will reproduce the problem?
1. Use "date-range" or "select" filters.
2. Be stuck with the default configurations of the two.

What is the expected output? What do you see instead?
I want to configure the datepicker behavior in a way other than the default.  I 
also want to limit the length of the <option>Display Text</option> in a 
selection field.

What version of the product are you using? On what operating system?
1.5.1, Windows

Please provide any additional information below.
I added two optional properties to the aoColumns object.
1.) A oDatepickerOptions property on a "date-range" filter will be passed 
through to the from.datepicker() and to.datepicker() functions.
2.) A iMaxOptionDisplayLength property on a "select" filter will be used to 
limit the length of the label used for an option.

Example use:

oTable.columnFilter({
    aoColumns: [
        { type: "date-range", oDatepickerOptions: { changeMonth: true, changeYear: true, showOtherMonths: true, selectOtherMonths: true }},
            { type: "select", iMaxOptionDisplayLength: 15, values: ["12345678901234567890", "1234567890"] },
        ]
});

In the drop-down selection list, the two options will be displayed as:
"123456789012..."
"1234567890"

Looks like this (nice) solution is not part of the latest version (1.5.6)? 
Besides, it would be nice to use the custom date format for the cell data as 
well. I use the same custom format in my table and in that case the range 
filter fails. I fixed this by changing the line:
dCellDate = $.datepicker.parseDate($.datepicker.regional[""].dateFormat, 
aData[_fnColumnIndex(index)]);

to:

dCellDate = $.datepicker.parseDate(from.datepicker('option', 'dateFormat'), 
aData[_fnColumnIndex(index)]);
