Leaks fix

[denar90]

Added:

• event namespace
• destroy method

TL;TR

I created simple example and made some profiling.

Here some example, which I used but I've done all work locally to reduce influence by jsfiddle or smth.

After destroying container with images, number of listeners more then at the beginning, also if look a second screen resize, scroll event listeners are present.

Another problem is namespaces, if we want to do destroy it's not possible without events namespaces.

So results of implemented solution are below and example is here.
