Issue #446: Adding 32-character length limit to User#username, Profile#first_name, Profile#last_name

opts[:person] set to empty hash only if not already defined.  same with opts[:person][:profile].  rake db:reset works properly again.

major hack on getting_started#2 with aspect javascript.  reload the page on ajax success on new aspect creation just to get it working.

users#getting_started route -> getting_started.  getting_started is now a mini-template referring to partials in users/getting_started/

user has a getting_started flag, set true by default.  aspect#index checks to see if getting_started flag is set.

IZ moved methods found in spec helper to helper methods file. now we can include them in the db scripts to keep friending behavior in sync
