Attempt to build with gradlew.bat fails

Describe the bug After installing android studio "Giraffe" and cloning the repo, I received an error attempting to build .

FAILURE: Build failed with an exception.

What went wrong:
A problem occurred configuring root project 'droidVNC-NG'.

I think I figured this out:

I didn't realize that the project included some sub-modules.

I recloned the repo and then ran:

cd droidVNC-NG/
git submodule init
git submodule update

I am familiar with cygwin, and tried to run bash gradew, but that failed with:

FAILURE: Build failed with an exception.

I switched to using the Android studio (Giraffe) and ran into an issue with the droidVNC-NG/app/src/main/res/values-televisioncolors.xml file.

I resolved this by copying the../values-night/colors.xml file over top of the symbolic link. The symbolic link didn't work inside the studio, most likely because I am on Windows. Perhaps the build just works on Macs or Linux machines?

I was able to build and deploy to the simulator.

I am curious as to why you didn't include a build.md file? I will try to put one together and open up a pull request.

My goal here is to hopefully be able to add support for keyboard events.

Nice to read you figured this out! I started a build instruction section in the README, you might want to have a look. And yes, using Unices here :-)
