Additional test for RString to test implementation.
Generic redirector for Inspect key calls.

Fix for PUB-590.

The fix introduces a new request class which
redirects based on key type (needs to fetch the value) to
a page serving value view.

Now the redirect is generic for all Models. If the value
is assignable to Model.class then the class redirects to
<model_name>View.html?source= page.

If the value is a frame, then the page redirects to Inspect2.
PUB-610: Add a force flag to allow overwriting existing files.

Total size of machine physical memory.
Add nodes run time into boot log information.

Be careful to change H2O.toString() method since H2O cloud hash
depends exactly on this method.

Hence, the fix introduces a new method H2O.toPrettyString showing
uptime of nodes.
Big warning regarding H2O.toString method.
