Better profiler (based on PR #29) 

Not sure if I had to create a new pull request here or at ludofleury:ludofleury.guzzle-profiler, related to pull request https://github.com/misd-service-development/guzzle-bundle/pull/29.

Basically what I did was use his pull request and changed the profiler to confirm with the comments in pull request #29. Here's a quick summary;

- Changed logo back to the original misd-service-development-guzzle-bundle
- Total times directly visible in the debugger toolbar and debugger menu (To make sure its consistent with other bundles that do this)
- Requests are listed in an UL, like some other debuggers (Doctrine, Logger)
- Changed the content to be somewhat the same like the LeaseWeb ApiCallerBundle, splitting information into timing, request and response per guzzle call. 
- Vanilla JS for toggling div display
- Removed all other dependencies (jquery, fontawesome, syntax highlighting)
- For viewing body content, you can chose raw, html or parsed (json), this idea came from ApiCallerBundle aswell

That's about it... All credits should go to @ludofleury for providing us the base that allowed me to do these changes.

Hope you like it!
