Better progress status in the console
Avoid new window in IE7 when posting coverage data

Dynamically adding a name to an iframe is not working in IE7. We now
use innerHTML to directly create the iframe with the name.
Bug fix: Call callback of Tests.run when manualStop

Previously, the callback was never called and only the return value was
used. This was problematic as the start of the server is asynchronous.
New method Server.prototype.addHandler

It is now possible to register a custom URL handler on the http server
Move cross browser functions to a dedicated file
Change the default way to report test status

The previous way using selenium was not scaling correctly to large test
suites (300 tests). IE7 was really slow and IE10 was reporting invalid
data.
We now post a form which is much faster and reliable (it was already
used for coverage data).

Note: The API of the onTest method of the Remote class  was changed
in a non-backward compatible way.
Rename SMPL_COVERAGE to PARAFFIN_COVERAGE
