chore(testing): Testacular config files + rake tasks

- adds testacular config files for jqlite, jquery, modules and e2e tests
- replaces obsolete JsTD Rake tasks with Testacular onces
- rake tasks are parameterazied so that they can be used locally as well as on CI server

usage:

rake test  # run all tests on Chrome
rake test[Safari+Chrome+Opera]  # run all tests on Safari, Chrome and Opera
rake test[Safari]  # run all tests on Safari
rake test:jqlite # run unit tests using jqlite on Chrome
rake test:jqlite[Safari,"--reporter=dots"]  # run jqlite-based unit tests on Safari with dots reporter
rake autotest:jquery  # start testacular with jquery-based config and watch fs for changes
rake test:e2e # run end to end tests
