Add Offsets, Generate Grids by Sass function

I've added Offsets to the grid system so we don't have
to fill up our websites with empty divs that contain spans
for spacing.

Spans and Offsets are generated using SASS functions to
cut down on the amount of code in the SASS Files and make it
more readable for developers.

We lose the ability to use @extend but that is not as important
as we minimize the css anyways.
Swap the colour of Alert and Attention Modules

I simply swapped the values of the variables $alert
and $attention since color-attention is driven by the
$attention variable we don't have to worry about changing
anything else
Add a startOpen option so tab will start open.

startOpen will run the toggle function once the tab
has finished loading. This will cause the tab to open.
Having it slide open reinforces to the user that this they
can toggle this functionality.
Change the color of .color-attention to $alert
Fixed naming of variables

- Added $red and $yellow to _mixins.scss
- $alert and $attention are now driven by new variables
- Changed .color-attention to be created from $red

wet-boew-slideout-open is default for open tab

Adding the class wet-boew-slideout-open to the slideout tab will
default the tab to the open state on page load.

It still slides open after load to imply that it's a tab.
