Using a file system path other than the default causes Undefined index: value in theme_status_report() error

In my site I have specifed a file system path of default/files/upload instead of default/files. I've adjusted my .htaccess accordingly and AIS works perfectly. A side effect of this configuration is that the requirements check on the Status Report page fails because the AIS .htaccess rules cannot be found. That's to be expected.

The problem is that in ais_requirements() a value element isn't set in the returned $requirements array, and that throws the following error: Notice: Undefined index: value in theme_status_report() (line 2583 of XXX/modules/system/system.admin.inc).

I haven't checked all of the possible status messages, but I think that some of the others are also missing a value element.

Thank you for this great module. It's really easy to use.
