Title: Visit page string

I wanted to be able to do this:

```ruby
Given /^I am using the (.+) search engine$/ do |engine|
@engineSearchPage = engine.capitalize+'SearchPage'
visit @engineSearchPage
end
```
So I added the ability for visit_page, on_page and if_page to take the page_object parameter as a String.

I also (in a separate commit!) changed the .rvmrc to run bundle install, inspired by the example:
https://github.com/YouthTree/TEDxPerth/blob/master/.rvmrc
because I forgot to run it myself at first and felt confused and stupid for about 5 minutes.
