Distinguish between projects and modules

[bartfeenstra]

.travis.yml.dist defines DRUPAL_TI_MODULE_NAME, which describes the project name, but not any specific module, since a project can contain multiple modules. In addition, DRUPAL_TI_SIMPLETEST_GROUP can probably contain multiple group names, but that's not really clear.

Any concrete suggestion on how to make this better?

[bartfeenstra]

Introduce DRUPAL_TI_EXTENSION_NAMES? A project can contain multiple modules, or can be a theme. Seeing as themes can contain PHP code, this is probably the most correct name?

I'm trying to run behat on a full website. Tthere isn't a specific module with its tests I want to run. The .travis.yml.dist seems to indicate (or at least encourage) that I put my tests into a specific module.
