Correct hooktest line in the README example for .travis.yml

[nevenjovanovic]

The hooktest script line in the example .travis.yml script (in the README) has one ./ too many. Currently the line reads:

script:  hooktest ./ --console table --scheme epidoc --workers 3 --verbose 5 --manifest --countword --allowfailure ./

When I tried to build with Travis using this, the hooktest refused to run. When I removed the first /., like this:

script:  hooktest --console table --scheme epidoc --workers 3 --verbose 5 --manifest --countword --allowfailure ./

... everything worked as it should
