local storage is not contained in profile

[chrysn]

different profile sessions (eg. as launched using the -c option) share a common local storage.

this seems to be not fully synchronized (saving to the local storage in one running instance does not make data visible to the other), but can be demoed like this:

* midori -c /tmp/profile1 http://html5demos.com/storage
* enter something in the "local" field
* exit midori
* midori -c /tmp/profile2 http://html5demos.com/storage
* see "something" written there

local storage should be private to the individual profiles. note that private mode appears to be unaffected by this.
