support setting enums by numeric values

As discussed in issue #13.

This also includes pull request #18, since this is not merged yet.

You really should learn to use feature branches ;)

My own workflow is as follows, I've found it quite simple and effective:

git fetch  # Fetches the current states of the branches
git checkout -b feature_XXY upstream/master  # Checks out a new branch, starting from where upstream/master is
*make changes and commit them*
git push origin feature_XXY  # Pushes the commits to a branch in origin (your fork)

This way, the new changes always start from where the upstream (in this case, my repo) is. For this to work, of course you need a remote pointing to "upstream": git remote add upstream git@github.com:kipe/enocean.git

By using this method, if pull request isn't merged, it doesn't affect anything and allows you to work on multiple issues/features at the same time. Also, if for some reason PR #18 isn't merged, it makes it very hard to merge this. If it was referencing the current master, it'd be a lot easier ;)

That being said, I'll try and leave work earlier and get these PRs reviewed and merged. For the future, I'd appreciate using feature branches referring to the current state of upstream though ;)
