Sorting by ID should be as "number" instead of "text"

[theali]

Now sorting is done by default "text" rule. ID is number so it should be sorted as number (20 > 3 but "20" < "3").

There is simple way to fix it:

1. Add number class to ID column in table http://wklej.org/id/381323/
2. Fix "number" type in tablesort (.* doesn't match \n, so there should be [\s\S]* instead). http://wklej.org/id/381324/

P.S. I don't know how to paste here diffblock, so I've used nopase "wklej.org".
