Monitor changes to fixtures folder.

I think the use of a fixtures directory is common enough that it should be covered by the default Guardfile.
Merge pull request #111 from andyw8/master

Configured Guardfile to watch for changes in fixtures directory
Update CHANGELOG. [ci skip]
Update rubygems source.
Do not output a failing runner html on startup. (See #112)

The Rails error page is too large to print to the console, just
show a message that more diagnosis information is available
at the runner url, which was printed to the console one line above.
Faster Jasmine runner exception detection. (See #112)

This adds a check to see if  Jasmine is available by looking
at `window.jasmine`. If so, the normal waiting for the spec
results happens until the given timeout is reached. If Jasmine
is missing, then it's very likely that an exception is show by
the Rails error page (which of course doesn't include Jasmine).
In that case fail the specs with the body text as error message,
so that diagnosis directly in the console is possible.
