27661	Move FileSystemFinder ImproperlyConfigured errors to system checks	Jerome Leclanche	Ling-Xiao Yang	"FileSystemFinder currently checks for the following on `__init__`:

- Whether STATICFILES_DIRS is a list or tuple, failing if it's not
- Whether STATICFILES_DIRS contains a directory equivalent to STATIC_ROOT

I'd like to suggest moving both of those checks to the Django system checks framework. As it is, they happen at runtime which delays when the error shows up."	Cleanup/optimization	closed	contrib.staticfiles	1.10	Normal	fixed			Accepted	1	0	0	0	1	0
