upgrade jongo version: 0.3 -> 0.4
fix: bug on collection sequence handling
change default loading mode to onrequest, many tests require that

for instance all tests involving mongo sequences
allow to compare non JSON responses
handle expected HTTP codes with no body

This will require test expecting a body consisting of only one line starting with a 3 digits number to add the 200 before.

So a then like:
800 beers

should now be written:
200

800 beers
