* add .golangci.yml and update dep
Prepare environment for https://golangci.com builds by installing
libcurl-dev.
Also update dep from 0.4.1 to 0.5.0
* Fix coveralls command in TravisCI script
* Unit tests Discover 90%
The NmapRun function needs a refacto to make it use adaptors instead of directly calling exec.Command, exec.Command.StdoutPipe, exec.Command.Start, bufio.Scanner.Scan and bufio.Scanner.Err
It makes me uncomfortable to push a test file that covers only 90%, but it's better than none, and the 10 missing %s are not very error-prone so it should be okay to delay this part a bit. For now it's more urgent to test as much of the code as possible
* Unit tests Helpers 100%
* Unit tests Loaders 100% - Attack 85%
Once again, the Attack functions are not as simple as the rest to unit test, so I will refacto all of this to use a CURL adaptor later, but for now the total is of 88.6% of coverage, which is good enough for something I spent 2 hours on
* Add testing to CI validation process
* CI now does functional testing with RTSPATT
* Change travis language to bash
