COM and HomeCtrl update

COM 2.1.0 and HomeCtrl updates are available.

I made updates to HomeCtrl and the COM framework. Most of all, the package name changed from org.atennert.* to de.atennert.*, due to the owned domain.

In the COM framework, I moved sources in COM from the sub directory to the main directory. I also made some additions in the build.gradle to push updates to bintray (jcenter). To add the library in your project you can use the repository http://dl.bintray.com/atennert/com and the dependency: group=de.atennert, artifactId=com with the wanted version.

Gradle example:

repositories {
    maven { url "http://dl.bintray.com/atennert/com" }
}

dependecies {
    compile 'de.atennert:com:2+'
}

I added a Readme.md to HomeCtrl. Besides that, there are several fixes and some pre work for new features, that can be seen from the commit statements.

Unfortunately, I'm missing release notes in both projects and a correct version overview in HomeCtrl. Both will be better in the future though.

HomeCtrl can be found at https://github.com/atennert/de.atennert.homectrl.

The com framework can be found at https://github.com/atennert/de.atennert.com on GitHub and as library via bintray https://bintray.com/atennert/com.
