Feature Request: roof & floor thickness based on thickness

[AK_Eric]

Currently you can set 'top solid layers' and 'bottom solid layers' : A fixed number of layers to print. Makerware lets you do this as well (I put the doc link below), but it also lets you set an alternate roof\floor thickness: For example, by setting the roof and floor thickness to .8mm, it'll be the same thickness regardless of any layer height changes: It's simply doing the math for you behind the scene.

I request this simply to get around human error: I have a 200micron layer-height profile that workeds good. I duped it and created a 100 micron profile. But I'd forgot to double my top\bottom solid layers. The end result was that my 100 micron print had roofs\floors that were half as think as my 200 micron profile, causing a lot of holes in the roof, and I have a ruined 23 hour print: My 200 micron print had 3 top\bottom layers, = .6mm of roof\floor. That means the 100 micron had 3 top\bottom layers, = .3mm of roof\floor. Or equal to 1.5 layers of a 200 micron print. just not enough to keep the rain out.

Sure, it's my fault for not going over all the settings on the new profile, but again, allowing the user to just set a constant fixed thickness for the roof\floor could only help.
