feat(jqLite): switch bind/unbind to more recent jQuery on/off

jQuery switched to a completely new event binding implementation as of
1.7.0, centering around on/off methods instead of previous bind/unbind.
This patch makes jqLite match this implementation while still supporting
previous bind/unbind methods.
