jquery-mobile warnings with jquery 3

[Cecilia Vela Gurovic]

jQuery 3 is deprecating bind and unbind methods. We already have the latest stable version for jquery.mobile.
There is a new alpha version but it doesn't change the touch event code that we actually use for mahara
https://github.com/jquery/jquery-mobile/blame/1.5.0-alpha.1/js/events/touch.js

since it hasn't been change in 2 years, we need to fix this bit of code.

According to the jquery site
https://github.com/jquery/jquery-migrate/blob/master/warnings.md
the solution is to change the method call to use .on() or .off()
