TODO: Rename `Route::over()` to `Route::hit()`

[Taufik Nurrohman]

The term hit is more appropriate to me. over seems to have missed the under, something that will never exist for routes because every success response will be immediately stopped by exit. So, even if we have Route::under() someday, then its callback function is likely will never be executed due to the exit expression at the end of the response.

Route::hit('foo/bar', function() {});

This method is in line with the Cache::hit() method so it is easy to scan and remember the API.

Possible extension that will be affected by this change:

• tag
• view

Consider to use if (Route::is('foo/bar')) {} where applicable since this method is likely will be exist forever.
