add travis and coveralls integration

make tests compatible with php 5.3

remove hhvm from travis

add coveralls integration

use old array syntax for php 5.3 support

add php 5.3 to the allowed failures for now

add build and coverage indicators to readme
I would not prioritize hhvm, I'd still include it on build list and allow
failures
