Type checks involving e_formTest

- MOD: e107::getTemplate() now accepts blank strings for the plugin name to mean
       that a core template should be loaded
- FIX: e_form::progressBar() now supports input values that already have % at the end
- FIX: Null check for $options['list'] in e_form::progressBar()
- NEW: Test rounding in e_formTest::testProgressBar()
