Set application id as application name

qtwebkit stores its cache and storage data in the paths

* @{HOME}/.cache/<application name>
* @{HOME}/.local/share/<application name>

To avoid that all applications store their data in the same directory we set the
application id as application name to make sure each application gets its own storage
directory.

Initialize XDG_DATA_HOME and XDG_CACHE_HOME home environment variables

If XDG_CACHE_HOME and XDG_DATA_HOME are not set webkit doesn't know where it should store
it's data for cookies, local storage, caching etc. We're using /media/cryptofs/.sysmgr as
base path here as this was also used in legacy webOS.

Fixes #465
