Update/Assess javascript resources

[laborg]

Some javascript resources are not up to date, which could mean that there compatiblity with new browsers might be a problem.
It would be helpful to minimize the usage of third party libraries (~software of unknown provenance). A javascript audit would be a good starting point. For corner cases, where a small feature might introduce a lot of javascript code the necessity of the features needs to be thoroughly reasoned.
