Changed .context display to inline-block from block

Hi Will,
When on a package page (for example, https://sublime.wbond.net/packages/R-Box), just above the package's name is a `BROWSE` link, with class `context`. It has the property `display: block`, which means that the hyperlink area extends all the way across the main `div`, not just the word BROWSE. If a user were to randomly click just below the search box, for example, they'd go to https://sublime.wbond.net/browse, which IMO is unexpected behavior. I edited ` /app/css/layout.scss` and `/public/css/app.css` from
```css
a.context, span.context {
    color: #999;
    display: block;
    font-family: 'Open Sans', Helvetica, Arial, Verdana, sans-serif;
    font-size: 1.4em;
    line-height: 1.2;
    margin-left: 0;
    text-transform: uppercase
}
```
to
```css
a.context, span.context {
    color: #999;
    display: inline-block; /* <-- */
    font-family: 'Open Sans', Helvetica, Arial, Verdana, sans-serif;
    font-size: 1.4em;
    line-height: 1.2;
    margin-left: 0;
    text-transform: uppercase
}
```
This changes the link area from stretching all the way across the `div` to just the text. I [searched](https://github.com/wbond/sublime.wbond.net/search?utf8=%E2%9C%93&q=context&type=Code) through all the code, and couldn't find any templates where this would result in different behavior than that described above, so this should be a pretty safe change.

Please let me know if you need anything else.

Thanks,
Matt
