Remove input[hidden] source for jsb data

[DracoBlue]

In the first version of jsb, it is possible to use:

<div class="jsb_ jsb_Name">
  <input type="hidden" value="key=value">
</div>

to load data.

Since everybody(?) uses the new:

<div class="jsb_ jsb_Name" data-jsb="key=value">
</div>

we might remove the hidden-input feature.

but then you loose the possibility to add more than one behavior to the same element.

for example: two behaviors with two different data-json values

<div>
  <input class="jsb_ jsb_Name1" type="hidden" value="key1=value1"/>
  <input class="jsb_ jsb_Name2" type="hidden" value="key2=value2"/>
</div>

i know this is a extreme case but currently possible.

@larslaade see #16, we're discussing that over there.

I think it's okay to remove the input-type-hidden feature when #16 gets a feasible solution. The older jsb versions still work w/ input type hidden and thus we just need to make sure the BC break is mentioned in prominent places. :-)

+1 and we have the benefit that data-jsb attribute can be optional, yeeaha!!
