Move Django template debugging to a separate plugin. Added Jinja2 template debugging implementation.
Fix broken import.
Remove unneeded pydb_frame argument.
Remove unused django_debug.py.
plugin_can_skip -> plugin_can_not_skip because default is False for plugin functions
Pass frame as argument.
Restored handling of conditions.
Remove django_frame.
null_func should be a method
Restored new_frame
Command uses tab as separator
Use itervalues instead of values to iterate.
Don't use is for string comparison.
Don't override __getattr__ to access plugin functions.
Minors
Inlined access to the PluginManager.
If we get an exception while printing the traceback, silent it and consider the debugging is finishing -- i.e.: return None for the dispatch.
Don't trace pluginbase lib.
Merge remote-tracking branch 'origin/template_debugging_merge' into template_debugging
bug with adding the same plugin fixed
