Wrapped fopen/close/read/write functions inside a simple "IOFile" class. Reading, writing, and error checking became simpler in most cases. It should be near impossible to forget to close a file now that the destructor takes care of it. (I hope this fixes Issue 3635) I have tested the functionality of most things, but it is possible I broke something. :p
