FundMe validation

Adding javascript to give alert when fields are left empty in the wizard. 
There's no need to add the name manually.  I have it in another branch right now, but there's a wrapper method now.

I'm gonna hold on merging this pr till that's in, but please clean out the name param.  Keeping DRY :)
