First test if the home page works

So far only the home page is implemented, so we test that.  We make use of the
Selenium 2 library to test if a page has a given text.
Moved .gitignore from robottests/ to /

It is possible to run Robot Framework anywhere in the project, so we need
to make sure that we are ignoring the generated files in all locations.

Before we only ignore the generated files inside the robottest/ folder.  By
moving .gitignore to root we can ignore the generated files in all locations.
