[Tizen] Do not use Crosswalk daemon when installing webapps

The Crosswalk installer shouldn't depend on the Crosswalk service
to be running in order to install applications. This is needed for
example to be able to install applications before the system has
booted.

BUG=XWALK-2028
Some times locale will change when we have some running apps, and we need to listen this event. When locale changed we can notify all running apps(in old logic we notify all installed apps) , so that the resource loader can load file from new locale path and the widget info will be refreshed.

Or we might have two other solution about this problem:
1. Relaunch all running apps after system locale was changed.
2. Ask system for locale every time we need this(for example when we need to load some resource form disk, we ask system for locale and use this locale to look for the correct resource)
