Better breakpoint management#177

When creating a version of a variable or utility at a certain breakpoint, and then changing the actual breakpoint size, everything gets really messy.

It would be great if the breakpoint is a variable, so that when changed, all attached settings for the utilitites and variables are also changed.
It really sucks to have to re-write everything if you changed a pixel in the breakpoint setting.
I also want to be able to create a template for new sites where i have lots of breakpoint specific behaviour, and possibility to just change the size before starting to code the new site. This isn’t possible right now as it all breaks when doing so.

I hope my explanation is sufficient, i don’t know how to better describe this right now.
But give it a try and hopefully you will see what i mean.
