Support cobertura

[ly-cultureiq]

i included the new node_modules - which makes it a huge diff. the only real commits are the first 3 - and the last commit is what changed after running npm install [email protected]

Being that this supports both lcov and cobertura - i took the liberty of changeng the param path-to-lcov to path-to-file but added a backwards compatible falback this also adds a coverage-format param that accepts lcov or cobertura
