fixed bug #1: accented letters in docroot
Refactored tests

cURL PHP extension is required in some tests. It now has a simple wrapper
function to avoid heavy code in the tests files. Given that it’s not basic code,
it’s tested too.
Tests files are also renamed to be automatically seen by phpUnit, and priorized.
Fixed light syntax typos and renamed Bottle_Response::delHeader() to deleteHeader()
