method_lookup drops session info

[Mike Rylander]

In the process of looking up a method for an internal subrequest, we lose session info. This is a problem when the subrequest makes a remote request, because then the subrequest can't look up the proper locale, among other things. The forthcoming branch passes the caller's session to the subrequest.

Here's the branch:

Pushed to master. Thanks, Mike!

Ended up having to revert. Since method_lookup() can be called as a class method, adding '&& ref($self)' to line 562 Application.pm was needed. While this fixed an issue calling ordinary methods, it didn't suffice for opensrf.system.method.all (i.e., introspection), apparently because of a data-structure cycle.

I've updated the branch to protect json-ification of method objects (used during introspection and remote method lookup) from accessing and including known-dangerous object members -- session, in this case. Leaving pullrequest off until someone else can point eyeballs at it.

I've pushed a squash of your patches along with a test case. Thanks, Mike!
