Catkinised phidgets_drivers metapackage (take 2)

[mintar]

This is the same pull request as #5, only with the history somewhat cleaned up. We haven't had time to test this on our hardware yet, so please wait a little before merging this.

Some things which are a little confusing at the moment:

• actually, ccny-ros-pkg/fuerte, ccny-ros-pkg/groovy, ccny-ros-pkg/hydro and ccny-ros-pkg/master all have identical code, which is somewhat obscured by the mass of merge commits
• muhrix/groovy also has all of those commits, again a little hard to see because of another set of merges

What I'd like to have in the end:

• ccny-ros-pkg/fuerte should point to the last commit before catkinization
• there should be a linear history of catkinization commits, starting with ccny-ros-pkg/fuerte
• ccny-ros-pkg/groovy and ccny-ros-pkg/hydro should point to the same commit, after the catkinization

What I've done in this pull request to do achieve that:

• rebased muhrix/groovy on top of ccny-ros-pkg/fuerte to get rid of redundant merge commits
• Squashed some commits that corrected mistakes in a previous commit into that commit (e.g. 4e196cf99d207b7375cda35176c678bdb51e7350), i.e. making it appear as if the offending file never was in the repo. This just makes the history more readable, the result is still the same.
• fixed the repository path in the README.md

What still needs to be done after merging:

git checkout hydro
git merge groovy
git push

Ok, I've tested this with our Phidgets Spatial 3/3/3 1044 on both Groovy and Hydro, and it runs without problems. Good work! I think you can merge this.

Great! Thank for testing!

[mintar]

Great! Now, could you also do the following (assuming you have ccny-ros-pkg/phidgets_drivers checked out as remote 'origin'):

git checkout -b hydro origin/hydro
git merge origin/groovy
git push
