Integration tests: choose device to run on

[Vanuan]

Steps to reproduce:

• connect device with debugging off
• start emulator (with debugging on)
• run mvn3 integration-test

Expected behavior:

• build system allow me to choose which device to use

Actual behavior:

• scala script (get-local-ip) fails with insufficient permissions for device

Sorry, there is a way: -Dandroid.device property.

Still, scala script skips emulator devices. Why's that?

[Vanuan]

BTW, is scala script used only for specifying host's ip? If it is, there's a better way: just use hardcoded 10.0.2.2
Review my pull request regarding Travis, please. #80

Oh, I should've read the wiki. So, scala script is used only for testing on real devices. For emulator 10.0.2.2 is used. Sorry about that.

[Vanuan]

For some reason, if I don't specify -Dandroid.device, host ip is my external ip, not 10.0.2.2

Ok, this is because scala script doesn't remove agit-integration-test.properties file
