Fix an issue that PD scrolling doesn't work so well

[Issue#]   P130919-00809
[Problem]  Scrolling in PD doesn't work well
[Cause]    WebKit decides scrolling operation after calculating timestamp of touch events,
           but timestamp format sent by Home is different to the format used by WebKit.
           which led the WebKit calculation incorrect, causing scrolling doesn't work well.
[Solution] web-provider creates timestamp that can be used by WebKit,
           and then sends it to WebKit using evas_event_feed function.
