Add the possibility to use custom unit instead of px.

[JoMas971]

Hello,

In some cases, we need to use a custom unit instead of px (%, vw, em...). So i've updated the plugin and add the possibility to do so. By default, it will use 'px' like before.

Regards.

Hi @JoMas971, I like this feature, but it works weird when using touch events to open / close the slideout.

this is very important feature. It would be nice if you would merge it. If not please what needs to be changed to meet your criteria for merging.

A function so necessary and that it does not merge is desecuting

I've modded my slideout install locally and it appears to work fine with units. I'll see if I can do some testing on mobiles and isolate any problems. My guess is it's only bad in certain cases that might be avoided.
