Fix some jquery deprecation warnings

Ths is a follow-on PR to
#241 in order to
fix the deprecation warnings:
* `bind()` replaced by `on()`
* `click(handler)` replaced by `on('click', handler)`

Three deprecation warnings remain, but they are caused by the
`jquery.tablesorter.js` plugin, so need to be handled upstream:
* Mottie/tablesorter#1787
* Mottie/tablesorter#1786

Related:
* #166
