Removed dashes from some non-core detects' names.

These dashes are preventing these detects from being queried in JS like every other test. For example, at the moment  one can use

```javascript
if (!Modernizr.fontface) {
    /* Do something. */
}
```

to test for `@font-face` support, but one must use

```javascript
if (!Modernizr["display-table"]) {
    /* Do something. */
}
```

to achieve the same for `display: table`. This introduces, of course, a backwards-incompatible change, but helps in keeping project-wide code style and library-wide naming consistency.
