Removed godep dependency.

Golang community are discuting a vendor aproach to go dependencies. This
change will come as experimental in go 1.5. For now I am removing the
godep dependency manager and using a vendor aproach.

I still have to use the full path when importing dependencies, but when
go1.5 released I just have to rename the imports and use a -vendor
prefix when building the project.
