Large cleanup

This commit is a large cleanup throughout the framework. Changes are:

- Put use statements on separate rules
- Fix some variable positioning in docblocks
- Import dependencies with use statement rather then using them directly with their namespace in a class
- Fixed an incorrect @param statement on a property docblock
- Fixed some incorrect return types
- Replaced stdClass with "object" (see note below)
- Replaced a static::make with a new Illuminate Response call in the Response facade (to be in line with the other functions)
- Added dependencies to the start function in the workbench Starter class

The reason why I replaced stdClass with "object" throughout all of the docblocks is because it isn't correct. Stating that you expect stdClass means that you don't expect any other class except stdClass which is wrong. You need to indicate it as "object" so you can expect different types of classes. A prime example is the migrator class where some functions expect a migration class. Those classes aren't stdClasses but they are objects.

Remember: all stdClasses are objects but not all objects are stdClasses.

Change typeBoolean from tinyint to bit
Updating tests
Fix container not removing bound instances on unset

You can return `null` or some integer from `fire` method as return code of execution
Increment version.
Add missing tab

Whoops, something went wrong here.
Made `freshTimestamp` return a Carbon object instead of DateTime

as Carbon is already used in database I think this is useful for unit testing

I can do `Carbon::setTestNow(Carbon::createFromDate(2000, 1, 1));` to fake the "created_at" field in an easier way.

I hope this will be merged in
Workbench starter follows symlinks.

Merge pull request #2262 from onigoetz/patch-4

Made `freshTimestamp` return a Carbon object instead of DateTime
Merge branch '4.0'
Fixed bug in default parameters that treat numeric 0 as null (or 'empty')
Added `disconnect()` method to DatabaseManager.

This method helps with unit testing where multiple connections are opened during a single PHPUnit process. Calling `DB::disconnect($name)` provides access to the protected `$connections` variable in a similar manner to `DB::reconnect($name)` but without recreating the connection. This prevents PDO Max Connection errors during database-heavy unit testing.
Changed to return void as `unset()` has no return value.
Fixed pattern filters with uppercase method names.
