Tycho Build

Jan please consider this pull request which makes it possible to build a product and an updatesite as described in #55. 

I had to change your version numbering from 4 to 3 positions where it was used (e,g, feature 2.1.0.4 was changed to 2.1.4.qualifer). This is needed in this continuous build environment. 

I added a product and a maven parent project. 

Before you pull, you can try out the new build environment by

git clone https://github.com/wimjongman/arduino-eclipse-plugin
mvn verify 

It builds against juno.

I have merged all the latest changes in the repo.

Cheers,

Wim
