Trailing slash messes things up

[nagydani]

If the requesting URL has a trailing slash, everything looks as if it worked, but trying to open the root namespace tree results in an unspecified error.

Recommended fix: strip the trailing slash

Fixed, trailing slash is stripped, and it now has a prefix (fluiddb being the main instance, and sandbox for sandbox). so: http://fluiddbexplorer.appspot.com/fluiddb/paparent/ point to "paparent" namespace on main instance
