add namespace packages to changelog
test for goto in loops that use e.g. empty arrays as input, #283
goto now also returns results for loops without input, fixes #283
use builtin repl completion after all, but written by us not the std lib module, which doesn't seem to work really, #280
test of repl autocompletion, #280
added a method 'api_classes.Completion.name_with_signs', because this is important for #280
rename name_with_signs to name_with_symbols
failing import tests for #280
first import tests for repl completion, #280
imports without path did have problems, because of an incorrect sys.path
fix a problem with testing setup_readline, when running all tests, this should also mean that #280 is now really finished
