Lint: Pass jquery.tablesorter.

Lint: Pass jquery.tablesorter.

Added tolerance for "onevar" (hard to dissect, many out-of-scope
usage, probably better to be done by someone who knows this code
better).

Errors:
* Strings must use singlequote
* '$cell' is defined but never used.
* 's' is defined but never used.
* Unnecessary semicolon.
* '$document' is defined but never used.
* 'sortOrder' is defined but never used.
* 'shiftDown' is defined but never used.
* 'table' is defined but never used.
* 'table' is defined but never used.
