Replaces gorilla mux to goji and decied to remove vendor dependencies from git (#28)

Removed the applicationContext stuff. Now every handler is a struct, and each one hold its dependencies.

* handler not handle

* Ignoring vendor dir

* Hide handlers complexity instantiation.

* Websocket handler does not need common handlers

* Use maps instead of for loops to search in memdb for apps (#29)

* Use maps instead of for loops to search in memdb for apps; use mutexes more efficiently by immediately unlocking when lock is no longer needed, not just at the end of the function via defer

* Fixed assignment to entry in nil map

* Minor impovements in source code
