Fix text color for buttons in Top Bar

When a button is used inside Top Bar, the text color was always getting set to the link color. However, a better default would be to use the button-style mixin from buttons.scss in order to determine what the best text color would be.
Added radius class to Reveal

If you add a radius class to reveal, it will inherit from global-radius by default.

[FEATURE] Add max-width and border-radius
Add a the class 'fixed' when navigation is 'stuck'

In line 117 the class 'fixed' is removed from the navigation without ever being added.

I assume the intention was to add a class to the navigation when it is stuck to the window so that additional skinning via CSS can be done (thats what i actually wanted to do but didn't find this functionality yet).
Browsing through the code i saw that you REMOVE a class 'fixed' when the navigation is 'unstuck' but you never add it.
This fixes that.

When the navigation sticks to the top it has the class 'fixed', as soon as it gets 'unstuck' the class is removed.
