2015-02-18[jsinterp] Disable comment supportPhilipp Hagemeister
We need a proper lexer to be able to understand YouTube's code, which contains /* inside of strings. For now it's sufficient to just disable comment support altogether. Fixes #4976, fixes #4979, fixes #4980, fixes #4981, fixes #4982. Closes #4977.
2015-02-01[jsinterp] Beef up and add testsPhilipp Hagemeister
