Added some test cases. Also now permit caller=>func() type of breakpoints. To make this work, I added a method, getCallingSite, to class InterruptSite and use this to walk the stack when checking if a site matches a break point that has more than one function name.
The debugger client now accepts feedback from the the debugger server about whether a breakpoint can be hit, absent further loads of files, classes or functions.
