Addresses Issue #27 https://github.com/alexweissman/UserFrosting/issues/27

I haven't tested but this should address issue #27. adding rememberance of input fields in case of failed registration.

I haven't tested this, so i would recommend someone does test it prior to merging the commit. The faster  this gets done, the faster i can move on to addressing some of the other issues such as improper comparison operator usage.
