32987	Warn user if they attempt to have mulitple templatetag libraries with the same name	Daniel	nobody	"If a project has mulitple apps with templatetags with the same module name, django will load each of them, but drop all but the last one, and not inform the user at all, making it quite hard to diagnose.

For example, if you have:

- blog/templatetags/navigation_tags.py
- news/templatetags/navigation_tags.py
- pages/templatetags/navigation_tags.py

then try to use them in a template:

{{{
{% load navigation_tags %}
}}}

then only one of these will be loaded - and there's no report that there is a problem - but if you attempt to use one of the filters / tags from one of the libraries that's not the loaded one, it throws a generic template syntax error saying it's an invalid tag / filter.

== Proposed solution:

Add a new 'check' to the django checks that warns the user if there are multiple templatetag libraries with the same name.
