Using gradle for building the project

This PR is not really meant to be merged yet. I created this to open up the conversation.

From the README.md:
"A pull request with a working maven integration welcome"

How about using gradle?

If I understood correctly, Gradle supports compiling everything, including the dependencies, which would be desirable for a wallet. Is my understanding correct? This does look promising.

I am not gradle guru. So, take my comments with grain of salt. Gradle supports multiproject-setups but it doesn't "natively" support making external maven projects as part of it's project structure. The good thing about gradle is that it has this scripting language built in. You can almost make anything with it - more easily than with maven.

You would like to always build the dependencies from the source as part of the build process of this project. I see two possible solutions.

• Make gradle always use only the local maven repo and manually build and install maven dependencies to local maven repo
• Or do it like here: http://stackoverflow.com/a/35796615
