Updated karma-requirejs to ~0.2.0.

#### Please check the issue #5 .
Updated karma-requirejs for `karma@0.10.10`.

#### Fixed the popup bug of input blur event.
It seems that the source old is not in the same version as dist.

In dist/ez-timepicker.min.js there are two functions:
```javascript
scope.updateFromInput()
scope.updateFromInput()
```
So I added these two functions to source code.
