Modify SymfonyRequestCollector

Cannot use the session bag anymore, so just change the collect function.
Fixes barryvdh#38 and fixes barryvdh#81

Only add openhandler when storage is set.

Redo custom logs

Disable exception

Maybe a bit scary or confusing..

Register PublisherServiceProvider

Fixes barryvdh#61 and barryvdh#56. The console service providers aren't loaded on web
requests by default, causing problems.

Pass $app instead of $debugbar

So we don't load any services in register()
See barryvdh#53

Revert a bit

Bump php-debugbar version

Require *

Remove git stuff
