Removed the UnconnectedUASInfoWidget class as it could be replaced with a simple QLabel with the same functionality. Also styled the NO UAS warning on the ReadOnly mission view so it looks good in both dark and light themes.

Switched button coloring so they're default grey with a :hover of blue instead of the other way around.

The View Only waypoint view is now styled similarly to the editable view. Same caveats apply where the widgets don't update their style if QGC has its styles changed.

The editable waypoint view has been completely reworked from a styling perspective. Now both the light and dark styles work great, though switching between the styles doesn't work as expected yet. That's still to come.

Further refinements of both the dark and light themes. The light theme is about 95% done, though the dark needs some more work.

The light and dark style sheets are now self-contained instead of only coloring. Both the have been synchronized, though the light style sheet still needs some adjustments.

Segregated the coloring of the UI from the rest of the styling in the CSS, so now style-base.css is loaded before the colorizing CSS files.

Removed the ICONDIR token from the CSS styles; it wasn't necessary and slowed down applying new styles to QGC.

Further styling changes to the outdoor stylesheet. The indoor sheet was modified as inline styles are removed from the C++ code.

Addressed issue #26. Select System, Plugins and System are disabled when neccessary. Removed style-outdoor-dark.css. Moved the other two .css files and Vera.ttf into files/styles.
