Fixes the issue about redirection to undesirable URL when clicked on the

file control selection button.

All our views are inherited from the Backform.Form (a extended
Backbone.View), which has an tag element set to 'form'. The default
action for a button in form is to submit the data, and that results into
undesirable redirection within our Views. We can resolve the issue of
redirection by setting 'preventDefault' to true in the click event
object on that button. But - we may use the button control within our
view in future, and that will have the similar behaviour. Keeping that
in mind, we set the default tag to 'div' instead of 'form' for all our
views.

ommit.
