fix(timepicker): width of hours/minutes input fields in template

[tschach]

The width of the hours/minutes input fields in the timepicker template is currently set by a "span1" in the class attribute:

<input type="text" ng-model="hours" ng-change="updateHours()" class="span1 text-center" ng-mousewheel="incrementHours()" ng-readonly="readonlyInput" maxlength="2">
...
<input type="text" ng-model="minutes" ng-change="updateMinutes()" class="span1 text-center" ng-readonly="readonlyInput" maxlength="2">

This causes a faulty width setting when timepicker is placed inside a "row-fluid".

I suggest to change this to "input-block-level":

<input type="text" ng-model="hours" ng-change="updateHours()" class="input-block-level text-center" ng-mousewheel="incrementHours()" ng-readonly="readonlyInput" maxlength="2">
...
<input type="text" ng-model="minutes" ng-change="updateMinutes()" class="input-block-level text-center" ng-readonly="readonlyInput" maxlength="2">

@tschach After @lazychino changes the width of inputs are set fixed to 50px. I think your problem does not occur anymore.

If not feel free to re-open.
