Make travis test php 5.3, 5.4 and 5.5

Currently these are all set to be allowed to
fail as currently some tests do fail but having
this run will allow us to slowly fix them and
remove the versions from allow_failures

The jobs for 5.3 5.4 and 5.5 seem to take somewhere
between 6 and 9 mins compared to hhvm which takes
about 4 but this should be no problem
