Improve masthead, hero overlay, and footer text alignment

[mmistakes]

To avoid awkward placement of masthead, overlay text, and footer links, left align all to line up nicely.

Much appreciate all this work - but is this change configurable? It completely changes the look of my site (which doesn't use the left-hand side-bar), spoiling it (IMHO). I love the theme though.

@casa-albore If the theme is working out for you no need to update if the change doesn't fit with your site. It's only cosmetic changes in the theme's CSS to better align things since it's meant to be a 2 column theme.

You can easily revert the changes back if you've already merged it in by looking at the commit and adding back the centering.
