Ipdbugger

Enabled activating the debugger during a run using signals:
windows: Ctrl+Break, linux: Ctrl+\
would raise an exception that the debugger can catch

- Fix AttributeError that occures when the checked Exception an attribute and not directly imported
- Fix syntax error 'extends'

Enabled passing parameters when using as a decorator

- Fixed pass bubble at the end of the function to also be applied properly when the last statement is complex (for, if,..)
- Added 'depth' parameter to debug, that also wraps inner function calls with debug (depth 0=don't wrap inner, 1=wrap one level, -1=wrap infinite levels down)

- Supported using debug on functions that use values from the current closure (like internals or temp functions)

* Don't catch exceptions inside try-except statements
