Subject: [PATCH] [IMP] web: add fail fast feature to qunit test suite

With this commit, we introduce a new 'fail fast' feature to our qunit
test suite: when it is activated, the qunit test suite will immediately
stop after the first failed test.

It is accessible as a flag in the url (failfast), or by clicking the
checkbox in the UI. It is currently not activated by default.

Note that this commit also change the url for the runbot phantomjs test
in order to activate this feature.  This allows us to increase the global
timeout for the js test suite without fear!
