Display out of space warning when ipad is full

I was banging my head against a wall trying to import to my ipad from yacreader library. Turns out i had a few movies on my ipad and it was full. The comic would start to import and then fail. The warning was not helpful so it would be nice if the app checked for space on the ipad for the comics it is importing and return a message when the comic size is > than the remaining space on the ipad.

Yeah, some of the error messages aren't that helpful, I will keep it in mind.
