Add Message attribute to the Page Title Should Be function

[rubygeek]

Many tests allow you to pass a message on failure, this function is lacking that. Though you can do something similar in other ways, it should be part of the function

One solution might be:

${title}=     Get Title
Should Be Equal   My Homepage    ${title}     Page didn't go to the right location

But better if we could do

Page Title Should Be  My Homepage  message=Page didn't go to the right location

Having a new argument sounds good idea.
