42tiny-js:

42tiny-js is partially more JavaScript compliant as the trunk-tiny-js
e.g.: trunk-tiny-js creates a var always when its needed but 42tiny-js only if the var the left-hand-side of an assignment-operator.

Test-scripts:
Some test-scripts in the "tests"-folder are not JavaScript compliant.
I have add new scripts according to the schematic: name.js -> name.42.js

run_tests:
run_tests is changed to prefer the ???.42.js files. Also run_tests is changed to run scripts in the "tests/42tests" folder after finished the tests from the "tests"-folder.
